WestJet Baggage Policy 2026: Carry-On Size, Fees, Pets

WestJet's carry-on limit is 56 x 23 x 36 cm (22 x 9 x 14 in), and wheels count toward it at the sizer. Econo, EconoFlex, Premium and Business guests get one carry-on plus one personal item. No kilogram limit is published, but you must be able to lift the bag into the overhead bin without help.

WestJet lists its bag sizes in centimeters first, then inches, so the 22 x 9 x 14 order differs from the usual US listing.

A WestJet personal item can measure up to 41 x 15 x 33 cm (16 x 6 x 13 in) and must fit under the seat in front of you. That size applies on every fare, UltraBasic included. A slim backpack or laptop bag works if it stays inside the 15 cm depth. No weight limit is published for the personal item.

No number is published for carry-on weight on WestJet. The written rule is that the bag must be light enough for you to place in the overhead compartment unaided, and WestJet offers help to guests with disabilities. Size, measured with wheels, is the limit agents enforce at the sizer.

UltraBasic includes 1 personal item and no carry-on bag, and you can't pay to add one. Two exceptions apply: trips to and from Europe and Asia, and bookings where Extended Comfort covers every flight in one direction, including connections. EconoFlex adds a free first checked bag, while Premium and Business include two.

Buying Extended Comfort seats for every flight in one direction restores the UltraBasic carry-on, which is the only paid way to get one.

On Econo within Canada and the U.S., the first checked bag costs $45 to $53 prepaid, $60 to $71 at online check-in and $70 to $83 at the airport. The second bag is $60 to $71 prepaid or $85 to $100 at the airport. UltraBasic pays more: $55 to $65 prepaid for the first bag. Ranges reflect taxes by departure airport, and fees are charged in CAD or USD depending on where the trip starts.

WestJet prices the same bag three ways, and prepaying online up to 24 hours before departure is the cheapest.

Econo guests flying to or from Asia get the first checked bag free. To Europe, the first bag on Econo costs $45 to $53 prepaid, and the second costs $110 to $130 prepaid on Econo and UltraBasic alike. UltraBasic pays $80 to $94 prepaid for a first bag on these routes but keeps a full carry-on. Third and fourth bags cost $200 to $236 online on international routes.

Each standard checked bag must weigh under 50 lb (23 kg) and measure no more than 157 cm (62 in) in length, width and height combined. You can check up to 4 bags, or 3 on WestJet Encore. WestJet does not publish an upper weight or size beyond which a bag is refused.

WestJet Encore regional flights cap you at 3 checked bags instead of 4.

WestJet's fee page charges $150 to $177 for an overweight or oversized bag on any fare. The main baggage page and help page still show $100 to $118, so we mark this fee as a conflict and use the fee page. No maximum accepted weight or size is published.

Four groups skip some bag fees on WestJet: - EconoFlex guests get the first bag free. - Premium and Business guests get two free bags. - Silver, Gold and Platinum WestJet Rewards members get two free bags, and Platinum adds a third. - WestJet RBC World Elite Mastercard primary cardholders and up to 8 guests on the same booking get one free bag when the card pays for the ticket. Benefits don't stack, so you get the single highest one.

The RBC card bag benefit covers up to 8 guests on one booking, a larger group than most airline cards.

Yes. Cats, dogs and birds can fly in the cabin for $50 to $59 within Canada and the U.S., or $100 to $118 elsewhere. The soft-sided carrier can't exceed 41 x 21.5 x 25.4 cm (16 x 8.5 x 10 in) and replaces your personal item, though UltraBasic guests may bring it in addition. Pets as checked baggage cost $100 to $118 in Canada and the U.S., with a 45 kg (100 lb) limit for pet and kennel.

WestJet accepts chinchillas, guinea pigs, hedgehogs and rabbits as checked pets, a wider list than its cabin rule.

No fee applies: WestJet checks child and infant equipment, car seats included, on top of the normal allowance. A lap infant can bring 2 pieces, such as a car seat, playpen or stroller. Fare-paying children get one piece free.

You pay 2 charges: the checked bag fee plus a service fee, and the bag goes in the hold. WestJet does not publish the service fee amount. The rule applies unless your trip touches Europe or Asia or you bought Extended Comfort for the whole direction.
