Montréal is served mainly by Montréal–Trudeau International (YUL), the city’s primary international and transcontinental hub, and the smaller Montréal–Mirabel (YMX), which now handles limited cargo and some charter flights. Trudeau typically hosts full-service carriers and many international and domestic low-cost options, making it the go-to for most travelers; Mirabel can be a budget-friendly pick for specific charters but is less convenient for city access. Trudeau sits about 20 km (roughly 20–40 minutes by car) west of downtown; regular options include the 747 express bus (around 30–45 minutes, modest fare), taxis or rideshares (20–40 minutes, fares varying by time and traffic) and airport shuttles. Pros: Trudeau usually offers extensive services, lounges and frequent connections. Cons: peak-hour road congestion and occasional higher fares for taxis or parking; Mirabel’s limited passenger services and greater distance can be less convenient for standard travellers.
Heathrow (LHR) is London’s primary international hub, handling most long-haul and premium carriers alongside major alliances; it typically feels more formal and service-oriented than the city’s budget airports. Located about 22–25 miles west of central London, the Heathrow Express reaches Paddington in around 15–20 minutes (higher fare), while the Piccadilly Line tube takes about 45–60 minutes for a lower-cost option; buses and taxis can vary with traffic. Pros: extensive lounges, wide route network and frequent transfers. Cons: can be crowded, longer security and transfer times and generally higher prices than other London airports. Gatwick (LGW) functions as a major secondary international airport serving a mix of full-service and low-cost airlines, often positioned as a cost-competitive alternative to Heathrow. It sits roughly 25–30 miles south of central London; the Gatwick Express reaches Victoria in about 30 minutes, while slower rail services or buses can take 30–60 minutes with lower fares. Pros: broad European and charter connections and competitive fares. Cons: fewer long-haul options than Heathrow and variable ground-transport costs depending on service chosen. Stansted (STN) is a primary base for low-cost carriers and European short-haul services, generally perceived as budget-friendly for leisure travellers. Located about 35–40 miles northeast of central London, Stansted Express trains take around 45–50 minutes to Liverpool Street, while coaches and taxis are cheaper but slower, often affected by road congestion. Pros: many low-cost routes and straightforward check-in. Cons: longer transfer times to the city and fewer premium amenities compared with bigger hubs. Luton (LTN) operates mainly as a budget and charter-oriented airport, commonly used by low-cost airlines and seasonal services. It’s around 30–40 miles northwest of central London; frequent shuttle buses link the terminal to Luton Airport Parkway station for a 25–40 minute rail trip into central London, while direct coaches take about 35–70 minutes depending on traffic and route. Pros: often lower fares and simple layouts. Cons: distance from the city center and variable onward travel times. London City (LCY) caters to business travellers and short-haul regional routes, typically positioned as a premium, convenience-focused airport due to its proximity and quick processing. Situated in East London, it’s roughly 6–8 miles from central Canary Wharf and the City; the DLR and a short taxi ride usually take 20–30 minutes to central business districts, with fares generally higher than tube journeys but quicker. Pros: very close to the financial district and fast transfers. Cons: runway constraints limit aircraft size and long-haul options, and fares can be comparatively higher.
