WestJet On-Time Performance in 2026
WestJet OTP, hubs, network, and how to predict and beat its delays in 2026 — for travelers across Canada and the US.
Headline numbers
WestJet (WS / WJA) operates from its primary Calgary (YYC) hub and growing operations at Toronto (YYZ) and Vancouver (YVR). 2026 OTP has trended modestly better than 2024 post-Sunwing integration.
- Arrival within 15 min (A14): ~75%
- Cancellation rate: ~1.2%
- Most reliable routes: YYC east-bound transcontinental
- Most delay-prone routes: YYZ west-bound in winter; transborder to congested US hubs
Why WS's OTP varies by season
Calgary has aggressive winter conditions and strong upper-level winds. WestJet's mainline 737 fleet is well-equipped, but inbound delay chains from US connections (especially from EWR, ORD, LGA) bite.

Frequently asked
Is WestJet more reliable than Air Canada?+
Operationally similar. WestJet's mainline OTP is competitive; AC's longer-haul network has different dynamics. Both vary heavily by season and hub.
