Montreal / Pierre Elliott Trudeau International Airport

Montréal-Trudeau International Airport (YUL) is the busiest airport in Quebec and one of only two Canadian airports to serve the full trans-Atlantic, trans-Pacific, and Latin American triad (the other being YYZ). It handled 23.5M passengers in 2024, securing its position as Canada's third-busiest airport and the principal eastern hub of Air Canada, which operates international widebody services from YUL using a mix of 787s and A330s. Positioned in Dorval 20 km (12 mi) west of downtown Montréal at 118 ft (36 m) elevation, the airport controls the primary eastern-Canadian gateway function — all arriving international flights from Europe and Africa into Canada first reach Canadian airspace in this sector. YUL operates three runways (06L/24R, 06R/24L, 10/28), with the longer 06L/24R at 11,000 ft handling widebody operations. The single integrated terminal complex, progressively rebuilt since 2000, merges domestic, trans-border (U.S. preclearance), and international flows into a tri-lobed jetty — one of the largest U.S. Customs and Border Protection preclearance facilities outside a U.S. airport, allowing passengers bound for 31 American destinations to arrive as domestic arrivals. A CAD 4 billion capital program announced in 2023 is adding a new international jetty, expanded baggage handling, and integration with Montréal's new REM light-metro system. YUL is Canada's principal French-language international gateway — a commercial distinction that makes it a natural transfer point for traffic between Paris, Casablanca, Algiers, and North America. Air France, KLM, Lufthansa, Turkish Airlines, Qatar Airways, and Royal Air Maroc all operate daily widebody services, and Transat's long-haul leisure operation is hubbed here, giving YUL a transatlantic route density that consistently ranks second in Canada.
