Calgary International Airport

Calgary International is Canada's fourth-busiest airport and the country's principal western gateway, handling roughly 19.4M passengers (2024) from a site of 20.8 sq km (8 sq mi) — making YYC the second-largest airport in Canada by land area after Montréal-Mirabel and the largest by airfield footprint west of Toronto. The airport sits 11 km (7 mi) northeast of downtown Calgary on the high plains at 3,557 ft (1,084 m) elevation, an altitude factor that shapes performance curves for long-haul departures. WestJet — Canada's second-largest airline — has its corporate headquarters and primary hub at YYC, operating Boeing 787-9 long-haul service to London-Heathrow, Dublin, Paris-CDG, Barcelona, Rome, Tokyo-Narita, and a Caribbean-Mexico leisure network. Air Canada and Air Canada Rouge maintain a substantial secondary hub with transcontinental and international service; WestJet Encore, Flair, Porter, and Lynx provide domestic coverage. International long-haul is rounded out by British Airways, KLM, Lufthansa, Air France, WestJet partners, and seasonal Icelandair. The route map reaches 142 destinations across 43 airlines, tied to Calgary's economic base in energy and to its role as gateway to Banff and the Canadian Rockies. Three runways handle operations, led by 17L/35R at 14,000 ft (4,267 m) — the longest commercial runway in Canada and among the longest in the Americas, built specifically to enable maximum-payload ultra-long-haul departures at the airport's elevation. The runway opened in 2014 as part of a C$2B expansion that also delivered a new international terminal and added roughly 10M annual passenger capacity. Two main terminals (Domestic/U.S. and International) are linked by a post-security walkway, and the U.S. preclearance facility on-site allows same-day connections into CBP-cleared U.S. destinations without re-screening.
