WestJet is Canada’s second-largest airline, founded in 1996 and based in Calgary. In recent years WestJet has significantly expanded through acquisitions, absorbing ultra-low-cost carrier Swoop (fully merged in 2024), integrating aircraft from the now-defunct Lynx Air, and completing the full integration of leisure carrier Sunwing Airlines in May 2025 — consolidating multiple brands under a single Air Operator Certificate.

Westjet Airlines Route Network
WestJet’s network spans an extensive domestic Canadian route map plus international routes to the US, Caribbean, Mexico, Central America, and select long-haul destinations, significantly broadened by its recent Swoop and Sunwing integrations.
Primary Hub
Calgary International Airport (YYC) & Toronto Pearson (YYZ)
WestJet operates dual hubs at Calgary International Airport (YYC), its original home base, and Toronto Pearson International Airport (YYZ).
Alliance & Partner Airlines
WestJet is not a member of Star Alliance, oneworld, or SkyTeam, but maintains an extensive network of bilateral codeshare and interline partnerships, including with Delta Air Lines, for connecting itineraries beyond its own network.
Baggage, Seating & Onboard Amenities
A quick reference before you pack — always confirm exact allowances on your fare rules at booking, since they vary by route and cabin.
Carry-On & Personal Item
Economy fares typically include one carry-on bag plus a personal item, with the lowest “Basic” fares carrying similar hand baggage allowances but more restrictions elsewhere.
Checked Baggage
Checked baggage allowance depends on fare class — the lowest “Basic” fares often exclude a checked bag by default, while standard “Econo” fares and above typically include one or more bags.
Excess Baggage Fees
Overweight, oversized, or extra bags typically incur a per-bag fee charged at check-in or online in advance — pre-paying online is usually cheaper than paying at the airport.
Seat Selection & Cabin Classes
WestJet offers Economy (Basic, Econo, Premium) and Business cabins on many routes, with seat selection sometimes chargeable on Basic fares and included on higher fare tiers.
How to Find the Cheapest Westjet Airlines Fares
Four habits that consistently lower what you pay.
Book in the Sweet-Spot Window
For most Westjet Airlines routes, fares tend to be most competitive when booked several weeks to a few months ahead of departure, rather than at the last minute or extremely far out.
Fly Midweek and Off-Peak
Tuesday, Wednesday, and Saturday departures are usually cheaper than Friday or Sunday, and red-eye or early-morning flights often undercut peak daytime departures.
Set Fare Alerts
Track your route and let price-drop notifications do the watching, instead of checking manually every day.
Price-Tracking Tip
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Use Flexible Date Search
Searching a date range instead of one fixed day often surfaces Westjet Airlines fares that are noticeably lower just one or two days earlier or later.
Check-In & Day-of-Travel
Online Check-In
Online and mobile check-in generally opens 24–48 hours before departure, letting you select or confirm your seat and download your boarding pass in advance.
Airport Arrival Times
Arrive with enough buffer for check-in, bag drop, and security — this matters more on international Aegean Airlines routes than short domestic hops.
Domestic vs. International Cutoff
International check-in and bag-drop counters usually close earlier relative to departure than domestic ones, so double-check your specific route’s cutoff.
