Flights, baggage allowance, onboard services, and travel information
•
IATA – Clearing House (code XB) is not an airline and doesn’t operate flights or accept pet bookings. Instead, IATA publishes global standards such as the Live Animals Regulations (LAR) that airlines, airports, and cargo handlers use to transport animals safely. The guidance below distills those widely used standards and common airline practices so you can plan with confidence. Always check the exact rules of your operating carrier and destination authority before you book.
Most airlines allow small, docile cats or dogs to travel in the cabin if the carrier fits entirely under the seat and the animal stays inside with the door closed. There’s usually a cap on the number of pets per flight and per passenger, and some routes or aircraft types don’t allow any. Trained assistance/service dogs are often permitted in the cabin at no extra cost, but require advance documentation and must remain harnessed.
Larger pets generally travel in the temperature-controlled, pressurized hold. Depending on the airline, they may be accepted as checked baggage on the same itinerary, or only via the cargo division. Expect seasonal and heat/cold embargoes, and note that brachycephalic (snub‑nosed) breeds face additional risk and are often restricted. Sedation is discouraged because it can affect breathing and thermoregulation at altitude.
For the cabin, airlines commonly require a leak-proof, ventilated carrier that fits under the seat; soft-sided models are often accepted. Typical size envelopes vary by aircraft, but footprints around 40–46 cm long, 24–30 cm wide, and 20–28 cm high are common; weight limits (pet + carrier) frequently fall near 5–8 kg. Because dimensions differ by airline and even by seat row, confirm the under-seat clearance for each segment.
For the hold, the IATA LAR calls for a rigid, secure crate tall enough for your pet to stand without the head or ears touching the top, and wide enough to turn and lie naturally. It must have metal-fastened doors, ventilation on multiple sides, absorbent bedding, and attached food/water dishes. Very heavy pets or oversized crates may be refused as checked baggage and routed as cargo; airlines publish maximum weight and size thresholds for each aircraft type.
Paperwork varies by route, but you should plan well in advance and work with your veterinarian. International trips often require microchipping before rabies vaccination, plus specific timing windows.
Keep printed and digital copies, and store extras in a sleeve on the crate. If you’re transiting, ensure the documents also meet the rules of the transit country.
Airlines charge per segment for pets in cabin or as checked baggage; cargo pricing is usually based on volumetric weight. Fees, acceptance, and booking windows vary widely, so reserve early and get written confirmation. On multi‑airline itineraries, the strictest policy usually governs.
Restrictions are common: many carriers accept only cats and dogs; rodents, reptiles, and most birds are often prohibited. Minimum ages apply, pregnant or nursing animals are frequently refused, and several countries (for example, the UK, Ireland, Australia, New Zealand, Hong Kong, and some island territories) have tight entry controls—often allowing pets only as cargo and never in cabin, except for recognized assistance dogs. Breeds with respiratory compromise may be barred from hold travel altogether.
Crate-train early so the carrier feels safe and familiar—short, positive sessions weeks in advance pay off. Exercise before departure, offer a light meal several hours before check‑in, and provide water without overfilling. Use absorbent bedding, secure the door, and label the crate with your contact details and “Live Animal” markings. Pack a small kit: spare leash/harness, wipes, extra liner, and a photo of your pet.
Aim for the most direct routing with generous connection times. In hot or cold seasons, choose flights at milder times of day. Discuss travel readiness with your vet and avoid tranquilizers unless a veterinarian explicitly advises otherwise. Underline your planning with one rule: always confirm with your airline and destination authority before you pay for tickets.
Although your search may show “IATA – Clearing House (XB),” that code belongs to the International Air Transport Association’s settlement system and is not an airline. There are no carrier‑specific rules under XB; when you fly, the policies that matter are those of the operating airline on your ticket. This guide gathers the practices most families encounter worldwide and helps you ask the right questions before you go. Because rules can vary by carrier and route, always verify details on your itinerary.
Most airlines define an Infant as younger than 2 years on the day of travel, a Child as 2–11 years, and an Adult as 12+ years. Some carriers treat 12‑year‑olds as children, others as adults, and unaccompanied‑minor services often cover ages 5–14. Newborn minimum age to fly is commonly 7–14 days, sometimes requiring a medical letter if earlier. If your journey mixes airlines, the strictest definition usually applies on segments flown by that carrier.
On many routes you may travel with an infant as a lap child, paying taxes and, on international itineraries, sometimes a percentage of the adult fare. Airlines generally allow one lap infant per adult; a second infant with the same adult typically must occupy a purchased seat. Buying a seat for your infant allows you to secure a restraint and often makes long flights easier for feeding and naps. For a seated infant, use an airline‑approved car seat or a certified child harness; placement is restricted to non‑exit rows, and window seats are often preferred to avoid blocking egress.
If you intend to bring a car seat, check that it bears an approval label from an aviation authority (for example, FAA/EASA) and that its width fits the assigned seat. Crew may ask to verify the label, and some aircraft types cannot accommodate certain seats at bulkhead rows. Seat assignments near the aisle ease trips to the lavatory, while bulkhead positions trade legroom and bassinet access for fixed armrests and limited under‑seat storage.
Lap infants usually do not receive a full checked‑bag allowance, but most airlines permit a small diaper bag as cabin baggage and will transport a stroller and car seat free of charge. Children traveling in their own seat typically receive the same allowance as the fare type booked for adults. Security agencies in many countries allow reasonable quantities of baby milk, formula, and purées beyond standard liquid limits—declare them separately and expect additional screening. Pack essentials in layers so you can remove liquids and wipes quickly at checkpoints.
The two-letter code XB does not belong to a passenger airline. It represents the IATA Clearing House — a back‑office mechanism used by airlines to settle bills with one another. Because it isn’t an operating carrier, there are no scheduled flights, no tickets sold to the public, and no consumer‑facing frequent‑flyer program. You can’t earn, redeem, or transfer miles with “IATA XB,” and there are no elite tiers to pursue. If you see XB referenced in industry data, think of it as plumbing that helps airlines reconcile accounts, not a brand you can fly.
To earn and use miles for trips that may involve multiple airlines, join the frequent‑flyer program of an airline you actually fly. Most programs let you credit flights from partner carriers, especially within alliances like Star Alliance, oneworld, or SkyTeam. Your miles usually accrue based on fare class, booking channel, and route, and some programs use revenue‑based formulas while others still credit by distance. Add your chosen program number to each reservation and check the accrual chart before you fly to avoid surprises. In short, pick a program that matches your routes and cabin choices, then funnel all eligible flights there — not to “XB,” which doesn’t accept any miles.
Because XB has no tiers, you’ll rely on the elite structure of your chosen airline program. Typically there’s a base level and then 2–3 elite tiers (often named Silver/Gold/Platinum or similar) that you qualify for via status miles/points or flight segments within a qualification year. Some programs also require a spend threshold; others do not, which can be friendlier to long‑haul economy travelers. If you fly a mix of carriers, choose a program whose tier credits recognize partners generously. It’s worth comparing how each program treats discounted fares and whether they count partner premium cabins fully toward status.
A smart path is to map your real travel: frequent short hops favor segment‑based programs, while long‑haul flyers benefit from distance‑heavy charts. Watch for status matches or challenges if you’re switching programs, and time runs near the start of a qualification period to maximize validity. Keep boarding passes until miles post; retro‑claims can rescue missing credit on partners. And remember that elite benefits are often recognized alliance‑wide, giving you value even when you’re not flying your “home” airline.
Redemptions are where partnerships shine. Most programs allow you to book award seats on partner airlines, mix cabins on complex itineraries, and sometimes include free or low‑cost stopovers. You can also use miles for upgrades on select partners, though fare class and inventory rules vary. Taxes, fees, and fuel surcharges can differ widely by carrier, so compare total costs rather than miles alone. Outside of flights, you’ll find hotel nights, car rentals, and merchandise — convenient but usually a poorer value than premium‑cabin flights.
The two‑letter code XB belongs to the International Air Transport Association’s Clearing House, an industry settlement function rather than an airline. It’s used to clear interline payments between airlines and partner companies, so it doesn’t schedule flights or carry passengers. Because it is not an airline, it owns no aircraft, sells no tickets under its own brand, and employs no flight crews. You might see “XB” in back‑office references on e‑tickets, fare‑construction lines, or accounting documents tied to your trip. When it appears, think financial plumbing—not a logo on a jet.
For fleet seekers, the answer is simple: the XB “fleet” totals zero aircraft. There are no types, registrations, or configurations to list because XB does not operate flights. Any airplane you board is provided by the marketing and operating airline shown by its own two‑letter IATA code next to the flight number (for example, AF123 or JL008). If your receipt mentions XB in tax or accounting lines, you’ll still fly on the operating carrier’s metal. To research the actual aircraft, follow the operating carrier’s code, not XB.
Since XB runs no airplanes, there are no seat maps, cabin layouts, Wi‑Fi options, or aircraft ages associated with this code. Those details depend entirely on the airline you’re flying—whether that’s a short‑haul narrowbody or a long‑haul widebody like a Boeing 787 or Airbus A350. The easiest check is to open your reservation, find the equipment code (such as 320, 738, 789, or 359), and consult the operating airline’s fleet page. Keep in mind equipment can change near departure, which is normal operationally.
There are no orders, deliveries, or retirements for XB because there is no fleet to manage. At the association level, IATA focuses on standards and financial infrastructure—settlement, risk management, and data formats—that help airlines operate more smoothly. Programs such as NDC and ONE Order influence how offers and orders are processed, but they do not represent aircraft purchases by XB. For real fleet pipelines, look to each operating airline’s commitments with Airbus, Boeing, Embraer, and others.
With no aircraft, XB has no direct emissions to reduce. More broadly, IATA members have adopted a goal to reach net‑zero CO₂ by 2050 and support measures like CORSIA and the scale‑up of Sustainable Aviation Fuel. These efforts guide the industry’s environmental trajectory, but they aren’t tied to an XB fleet because one doesn’t exist. If sustainability matters for your trip, check the operating airline’s SAF options, average fleet age, and efficiency features on the specific aircraft you’ll fly.
If your itinerary references the IATA code XB, here’s the key detail: XB is not an airline. It denotes the IATA Clearing House, a financial settlement service within the International Air Transport Association, so it operates no aircraft, has no cabins, and provides no onboard catering. When you see XB, it’s a back‑office billing marker rather than a carrier you’ll fly. Your meal service will be decided by the actual operating airline shown on your ticket (look for the line that says Operated by). To plan your dining in the sky, identify that airline and route; the guidance below outlines what most passengers can expect across the industry once you know who is flying you.
On short routes (roughly under 2–3 hours), many full‑service carriers offer complimentary soft drinks and a light snack in economy, while others use an buy‑on‑board menu; business class typically receives a plated light meal or hearty snack with bakery items. Medium‑haul flights (around 3–6 hours) usually bring a hot meal or substantial cold tray in economy with a second snack service on longer sectors, and a multi‑course service in premium cabins. Ultra‑short, high‑frequency flights may simplify catering to speed up service, while red‑eyes often prioritize rest with a condensed “supper” and breakfast. On long‑haul (6+ hours), economy passengers generally receive a full hot meal after takeoff and a lighter second service before landing; premium economy adds more choice and larger portions. Business class typically features multi‑course dining—starter, main, dessert, and often cheese—served on china, with better wines and espresso‑style coffee on some routes. First class, where offered, leans into restaurant‑style plating, broader selection, and sometimes flexible timing such as dine‑on‑demand. Low‑cost carriers can differ markedly, relying on paid menus even on longer flights, so checking your specific airline is essential.
Most full‑service airlines support special meals for common dietary and religious requirements, including vegetarian and vegan, gluten‑free/celiac, low‑lactose, low‑salt, child and baby meals, as well as kosher and halal. These are usually requested through “Manage Booking” as a Special Service Request; timelines vary but are commonly 24–48 hours before departure (some meals like kosher or Jain may require up to 72 hours). Airlines aim to minimize cross‑contamination, yet cabins are not sterile environments, so while nut‑free or allergen‑free trays may be offered, complete guarantees are rare. If your needs are strict, pack sealed snacks that meet security rules and carry a doctor’s note if you use medical devices such as auto‑injectors. If you’re connecting across multiple airlines, place a request for each segment and re‑confirm after any schedule change. For gluten‑free travelers, a GF option is widely available on long‑haul; still, bring backups like bars or crackers in case of last‑minute catering swaps. Vegans and vegetarians will usually find a dedicated hot meal on medium‑ and long‑haul; short‑haul availability can be inconsistent. Parents can pre‑order child meals to get kid‑friendly flavors and earlier service, which helps settle younger travelers.
Seeing “XB” on a ticket can be confusing when you’re trying to figure out what movies or Wi‑Fi you’ll have onboard. Rather than pointing to a single airline, it signals an industry billing code that sometimes shows up in bookings. Because of that, your in‑flight entertainment isn’t tied to XB at all—it’s shaped by whichever airline operates the aircraft. The guidance below shows how to find out what to expect and how to get the most from it.
XB is the two‑letter designator used by the International Air Transport Association (IATA) Clearing House. It’s an accounting identifier, not a passenger airline, so XB does not operate aircraft, publish seat maps, or maintain an onboard entertainment catalog. If your itinerary shows XB, look for the line that reads “operated by …”—that named airline is the operating carrier. The IFE you’ll experience comes entirely from that airline and that aircraft type. Keep this in mind as you read the rest: every feature depends on the operating carrier, not on XB.
Most modern carriers offer a mix of movies, TV series, music, podcasts, and casual games, either through seatback screens or a bring‑your‑own‑device portal. On long‑haul jets, you’ll usually find personal seatback screens with hundreds of hours of content and a simple touch interface; shorter routes may rely on streaming to your own phone, tablet, or laptop. Access to streaming portals often requires connecting to the aircraft’s Wi‑Fi network (no internet purchase needed) and, on some airlines, opening their app. Expect basic playback controls, language options, and parental locks, though the depth of features varies by airline and aircraft type. To stay comfortable, bring your own wired headphones—Bluetooth support on seatback systems is growing but is not yet universal.
Content breadth generally scales with route length and aircraft size. Long‑haul fleets tend to feature recent Hollywood releases, international cinema, complete TV box sets, kids’ zones, destination guides, and curated music channels, often refreshed monthly. Many systems now include accessibility features such as closed captions, multiple subtitle tracks, and audio description on selected titles. Picture quality ranges from standard definition to crisp 1080p on newer screens, and sound quality improves noticeably when you use decent headphones. On regional or low‑cost flights, the catalog may be slimmer or limited to a streaming portal with a rotating selection.
In premium cabins, you can expect larger, higher‑resolution screens, headphones (often noise‑canceling), and extra content like full seasons, live TV, or an expanded music library. Economy seats typically have smaller screens or streaming‑only access, and headsets are either complimentary on long‑haul or purchasable on shorter trips. Seat power—USB‑A, USB‑C, or AC—helps keep devices alive, but availability still varies by aircraft, so it’s wise to board with a full charge. Families will appreciate kid‑safe profiles and PIN controls where offered, though setup steps differ by airline. If no built‑in IFE is installed, many carriers supplement with free magazines or destination videos accessible via the portal.
Compact strollers can often be taken to the gate and gate‑checked; larger models may need to be checked at the counter. Tag your stroller early, remove accessories, and consider a protective bag. On arrival, gate‑checked items are usually returned at the aircraft door or the jet bridge, though some airports deliver them to the baggage belt.
Many long‑haul aircraft offer bassinets at bulkhead rows, but numbers are limited and weight/length limits apply. Request a bassinet as soon as you book and reconfirm before departure; assignments remain subject to aircraft type and safety rules, and the bassinet must be stowed during taxi, take‑off, and landing. Even with a bassinet request, always plan a backup sleep strategy, such as a wearable carrier and a familiar blanket.
Children’s meals are commonplace on international services and must be requested at least 24–48 hours before departure. Baby meals are less consistent, so carrying your own supplies is wise; cabin crew can usually provide water for formula and help warm items where equipment permits. Many airlines offer family preboarding or early boarding for those needing extra time, which helps you settle in and secure overhead space. Seatback programs and streaming libraries include kids’ content on longer flights; bring child‑safe headphones, books, and a small surprise activity to rotate during the journey.
International travel with minors may require a passport, visas, proof of age, and sometimes a notarized consent letter when one parent or guardian is absent. Some countries require birth certificates for domestic flights or vaccinations for entry; carry originals or certified copies where applicable. Keep medication in original packaging and a doctor’s note for any temperature‑sensitive items. Aim for generous connection times, especially with strollers or bassinets that must be reissued between flights.
While XB (IATA Clearing House, code XB) does not set passenger rules, aligning your plans with the operating carrier’s policies—and building a little extra time into your day—will make flying with little travelers smoother. A few early confirmations and thoughtful packing go a long way toward a calmer, safer trip for everyone onboard.
When planning awards, flexibility pays off. Try alternate dates or nearby airports, search segment‑by‑segment, and consider off‑peak pricing where available. Some programs let you hold awards briefly while you finalize plans. If you have bank points that transfer to multiple airlines, move them only when you’ve confirmed award space — once transferred, they’re usually irreversible.
While specifics vary, elite status commonly unlocks priority check‑in and boarding, preferred or extra‑legroom seats, and additional baggage — perks that smooth your journey across many partner airlines. Mid and upper tiers often bring lounge access on international itineraries, though local rules may restrict entry on purely domestic trips. Irregular operations support can improve with status, giving you better rebooking options during disruptions. Seat selection fees and same‑day changes may be reduced or waived depending on tier.
Alliance recognition is key. In Star Alliance, Gold members typically receive lounge access and priority services network‑wide; Silver is more limited. In oneworld, Sapphire and Emerald confer broad benefits (with Emerald adding First Class lounge access where available), while Ruby is lighter. In SkyTeam, Elite Plus usually brings lounge access and priority benefits, with Elite offering a subset. Use these cross‑carrier privileges to maintain a consistent experience even when you aren’t flying your primary airline.
Even without an “XB” program, you can extract strong value by aligning with one carrier’s scheme and its partners. Focus on earning where you redeem, keep good records, and lean on alliances to stitch together complex trips smoothly. A few practical habits can multiply the payoff:
, because it isn’t an airline at all — it’s financial infrastructure for airlines. Your strategy should be to pick a real airline’s program, earn across its partners, and redeem where award space and fees line up in your favor. Elite status then adds comfort and priority across the alliance, not just on one carrier. With a little planning, you’ll get the benefits of a worldwide network — even though XB itself stays firmly behind the scenes.
XB functions as a “pseudo‑carrier” code for clearing and accounting, not for passenger operations. You won’t see XB flight numbers on departure boards or painted on tails, and you can’t buy a ticket marketed by XB. In fare construction and industry documents, you may encounter other neutral references—such as “YY”—that also don’t equate to a real operating fleet. When researching your aircraft, rely on the two‑letter code of the marketing or operating airline printed next to your flight number and ignore XB for fleet details.
Expect water, juices, and tea/coffee across most flights; short‑haul economy may charge depending on airline policy, while long‑haul usually includes them. Alcohol availability varies: some carriers provide beer and wine free of charge in economy on long‑haul but sell spirits, while premium cabins tend to feature curated wines and a broader spirits list. Legal drinking age and local laws apply, and you generally cannot consume your own alcohol onboard—only crew‑served beverages are permitted. On late‑night services, crews may pace service to protect sleep, but you can always request water; consider alternating alcoholic drinks with water to stay hydrated in the dry cabin air.
Quality hinges on route length, cabin, and the airline’s catering base, yet the broader trend is toward fresher menus, regional sourcing, and reduced single‑use plastics. Many carriers collaborate with notable chefs, restaurants, or coffee and patisserie brands—if your operating airline does, it’s usually highlighted on its website and inflight magazine. Economy meals aim for broad appeal and stability in reheating, while premium cabins focus on choice, presentation, and better beverage pairings. Digital menus in apps or seatback screens are increasingly common, letting you preview choices and sometimes select entrées in advance.
Because XB doesn’t operate flights, the best results come from preparing with the actual airline you’ll board. A little homework ensures you’re fed the way you prefer and avoids surprises, especially on tight connections or late‑night departures.
Inflight connectivity is provided at the discretion of the operating carrier, with coverage and pricing influenced by the satellite network and the route. Many airlines now include limited free messaging, while full‑internet plans are time‑ or volume‑based, and voice calls are typically blocked. Streaming quality for onboard portals does not require buying internet; you simply join the cabin network and launch the IFE website or app. A few carriers also stream live TV or sports on select aircraft, though availability can change mid‑fleet during retrofits. If staying productive matters, verify Wi‑Fi availability on your exact flight in the airline’s booking or manage‑trip pages before you fly.
Because XB is not an airline, there are no XB‑specific media partnerships; you’ll enjoy the catalog curated by the airline that operates your flight. Most carriers license from major film studios, regional networks, and music labels, and some collaborate with audiobook and podcast platforms. Increasingly, airlines strike branded tie‑ins with streaming services—think curated playlists or a rotating selection of originals—though these vary widely and may be route‑restricted. On codeshares, your ticketing brand does not affect the catalog; the onboard system is owned and programmed by the operating airline. If a particular show or genre is essential, check the airline’s website or recent passenger reports for the current lineup.
With a little preparation, you can turn a routine flight into a genuinely relaxing stretch of screen time. The most important step is confirming who flies the aircraft, since that determines everything from screen size to Wi‑Fi. A quick app download at home can save frustration when a streaming portal requires it in the air. Bringing your own lightweight headset and charging cable upgrades both comfort and sound. If you’re traveling with kids, setting up profiles and downloaded backups ahead of time keeps everyone happy even if the onboard catalog is busy or briefly offline.
XB (IATA‑code: XB) represents the IATA Clearing House and not a passenger airline, so there’s no single set of in‑flight entertainment features to describe. What you experience will be exactly what the operating carrier provides on that aircraft, from seatback screens to Wi‑Fi and streaming portals. By confirming the airline and aircraft in advance and preparing your devices, you’ll make the most of whatever system is onboard. When in doubt, consult the carrier’s website or your booking’s manage‑trip page for aircraft‑specific details. With a little planning, you can count on a smooth, enjoyable IFE experience—no matter whose code is on the ticket.
