WestJet baggage allowance, by fare

Most airlines' cheapest fare restricts the checked bag and leaves the cabin bag alone. WestJet's UltraBasic fare goes further on North American routes: it strips out the full-size carry-on entirely, leaving only a personal item that fits under the seat -- the same restriction Air Canada applies to its own cheapest fare.

Cabin bag and personal item

The personal item (41 x 15 x 33 cm) is free on every fare. The full carry-on bag (56 x 23 x 36 cm) is free on every fare except UltraBasic on domestic and transborder routes, where it's simply not included at all. Check your bag against WestJet and 52 other airlines with our carry-on checker.

Checked baggage by fare

Checked bags top out at 23 kg and 157 cm total dimensions under normal pricing; bags between 23-32 kg or oversized cost $150-177, and anything over 32 kg has to go through WestJet Cargo instead. Prices for prepaid bags rise if you wait until self-serve check-in or the airport counter.

Status and the co-branded card

WestJet Rewards Silver and Gold members get their first two bags free; Platinum members get three. The WestJet RBC World Elite Mastercard is unusually generous here -- it waives the first bag not just for the cardholder but for up to 8 guests traveling on the same booking.

Bottom line

If you're booking UltraBasic for a North American WestJet flight, budget for a personal item only -- your usual roller bag won't make it into the cabin free. See our carry-on vs. personal item guide for what actually clears that smaller allowance.
