WestJet Busiest Domestic Routes in 2025

CALGARY- WestJet (WS) operates numerous busiest domestic routes in the Canadian airspace in 2025, and Calgary serves as the primary hub for most of its traffic. The carrier’s Western Canada bias is evident, with most routes operating to or from Calgary, Vancouver, or Edmonton. These hubs host both short-haul regional connections and long-haul domestic services across the country.

Calgary (YYC) is WestJet’s busiest hub by far. It appears in 26 of the top 37 domestic routes. These vary from short-haul flights such as Calgary–Edmonton to long-haul links such as Calgary–Toronto and Calgary–Halifax.

The Calgary–Vancouver route is WestJet’s busiest domestic route with nearly 1,000 monthly flights, and is also the busiest in terms of seats offered. On transcontinental routes, Calgary–Toronto and Calgary–Halifax are the busiest in terms of ASMs. The strong hub-centric operations allow WestJet to connect smaller cities like Comox, Regina, and Moncton with the rest of Canada through Calgary efficiently.

Top Routes by ASMs

Calgary–Toronto led all WestJet domestic routes in available seat miles with approximately 163.7 million ASMs in June 2025. This is due to the high frequency, aircraft size, and sector length.

Toronto–Vancouver follows with 141.5 million ASMs, despite fewer flights, due to the longer sector length. Edmonton–Toronto ranks third, with over 88.6 million ASMs, despite fewer flights, indicating WestJet’s commitment to transcontinental access.

Other high ASM domestic long-haul routes are:

• Halifax–Calgary: 73 million ASMs
• Ottawa–Calgary: 64 million ASMs
• Montreal–Calgary: 38.5 million ASMs

WestJet’s transcontinental flights, though lower in frequency, contribute the most ASMs due to longer flight times and heavier aircraft deployments.

Broader Network Trends

In addition to Calgary, the airline offers strong connections to other major cities.. Toronto–Vancouver, Edmonton–Vancouver, and Winnipeg–Calgary all rank highly in terms of both frequency and seat count. While eastern markets are not as much of a priority in WestJet’s domestic strategy, there are nevertheless several longer-haul connections from Calgary to destinations like Toronto, Halifax, Montreal, Ottawa, and St. John’s.

Short-distance regional and intra-provincial flights such as Edmonton–Calgary, Kelowna–Calgary, and Edmonton–Kelowna also feature prominently. These shorter sectors have a larger number of flights but lower ASMs due to distance.
