Cheap Flights from London to Toronto Starting at $329

London is served by a network of airports with distinct roles, so travelers should pick by budget, airline, and convenience. Heathrow (LHR) is the main international hub for long-haul and full-service carriers, typically pricier for flights but offering excellent connections; it sits about 20–25 km west of central London, reachable by the Heathrow Express (15–20 min, premium fare), the Elizabeth Line or Underground (30–50 min, lower fares), and regular taxis (40–60 min, higher cost). Gatwick (LGW) operates as a large international and leisure gateway with a mix of legacy and low-cost carriers, around 45 km south; the Gatwick Express or Southern/TfL services take 30–50 min, while coaches and road options can take longer. Stansted (STN) and Luton (LTN) are typically budget- and charter-oriented, farther out (35–70 km north/northwest) and often cheaper for tickets; coach and rail links vary from 30–75 min depending on service, with low-cost airport transfers commonly available. London City (LCY) is a compact, business-oriented airport close to Canary Wharf (around 10 km east), usually favored for short-haul business routes with quick transfers by DLR or taxi (15–30 min). Pros: wide airline choice across airports, good public transport integration. Cons: some airports can be far from central London, which may add time and variable transfer costs; low-cost terminals can mean fewer on-site amenities.

Toronto is served primarily by Toronto Pearson International (YYZ) and Billy Bishop Toronto City Airport (YTZ), with smaller general-aviation and cargo fields nearby. Pearson, northwest of downtown in Mississauga, functions as the region’s main international hub and typically hosts full-service carriers alongside many foreign and domestic connections; fares can be mid-to-high depending on season and carrier. It sits about 25–28 km from the city center, reachable by the UP Express train in roughly 25 minutes (tickets usually mid-range) or by taxis and rideshares in 30–45 minutes depending on traffic. Pros: extensive lounges, many transatlantic and long-haul options, and frequent ground links; cons: busy at peak times and potentially longer connection walks. Billy Bishop (Toronto Island) is a compact downtown airport on the harbour, often positioned as a convenient, short-haul alternative for regional and US flights operated mainly by smaller and low-cost regional carriers. It’s only about 2–3 km from the core; access is by a short pedestrian tunnel, ferry (a few minutes plus queuing), or water taxi, usually adding minimal travel time compared with road transfers. Travel times to Union Station can be under 15 minutes, with modest fares for ferries and short taxi trips. Pros: proximity to downtown and fast turnaround; cons: limited long-haul options and fewer amenities compared with Pearson.
