Cheap Flights from London to Calgary — $347

Heathrow (LHR) is London’s primary international hub, handling the majority of long-haul and premium carriers as well as some full-service European airlines; it’s often seen as pricier than regional options. The airport sits about 20–25 km west of central London, with the Heathrow Express taking roughly 15–20 minutes to Paddington (higher fare), the Elizabeth Line offering a slower but cheaper 30–40 minute option, and taxis or ride-shares taking 30–60 minutes depending on traffic. Pros: extensive international connections, wide facilities and lounges; cons: larger terminals and potential for longer security and transfer times. Gatwick (LGW) functions as a major international and leisure gateway served by a mix of full-service and low-cost carriers, and fares can be moderate to low depending on season. Located approximately 45 km south of central London, the Gatwick Express reaches Victoria in about 30 minutes (premium ticket), while Thameslink and Southern trains take 30–50 minutes for cheaper fares; road transfers take around 60–90 minutes. Pros include a compact two-terminal layout and good European connectivity; cons include fewer long-haul options than Heathrow and variable transfer times by road. Stansted (STN) is typically known as a budget and regional airport, popular with low-cost carriers and many European routes, which can mean lower fares but fewer premium services. It lies about 50 km northeast of central London; Stansted Express trains take around 45–50 minutes to Liverpool Street with mid-range fares, while coaches to Victoria or other hubs may take 60–90 minutes at lower cost. Pros: strong low-cost airline presence and frequent departures; cons: greater distance from the centre and sometimes limited late-night services. Luton (LTN) mainly serves low-cost and holiday airlines and is often perceived as one of the cheaper access points to London, though additional transfer costs can apply. The airport is roughly 35–45 km northwest of central London; Thameslink trains and shuttle buses connect to central stations in about 30–50 minutes, while coaches and taxis can take 60–90 minutes depending on traffic. Pros: competitive fares and a focused low-cost offering; cons: smaller terminals and added time/complexity for transfers. London City (LCY) is a niche, business-oriented airport with a compact layout and primarily serves short-haul and business routes operated by full-service carriers and regional airlines. Located very close to Docklands, it’s about 10 km east of central London, with DLR and tube connections reaching the City in 15–25 minutes at modest fares; taxis are typically quick but can be pricier. Pros: proximity to financial districts and fast check-in; cons: limited long-haul flights and stricter aircraft/weight limits that restrict some services.

Calgary International Airport (YYC) is the region’s primary international gateway and usually operates as a full-service hub with a mix of legacy carriers and low-cost airlines serving domestic and transborder routes. It’s about 9–15 km northeast of downtown Calgary; travel times range from roughly 15–30 minutes by taxi or rideshare and around 30–45 minutes by public transit (Blue Line light rail plus a short shuttle), with fares typically in the low single digits for transit and higher for taxis. YYC tends to be perceived as mid-range in price — competitive on West Coast and domestic flights but can be pricier for long-haul connections. Pros: modern facilities, ample lounges and immigration services; cons: can be busy during peak oil-and-conference seasons and slightly farther from the core than some smaller regional airports.
