WestJet's free allowance is a personal item of 41 x 33 x 15 cm. The larger 56 x 36 x 23 cm cabin bag is all fares except UltraBasic — check the fare, not the bag.
| Bag | Max size | Max weight | Notes |
|---|---|---|---|
| Personal item (free) | 41 x 33 x 15 cm | — | Must fit under the seat in front. |
| Cabin bag (all fares except UltraBasic) | 56 x 36 x 23 cm | — | Must go in the overhead bin without help from the crew. WestJet publishes no weight figure — the test is that you can lift it yourself. |
The basic fare includes no checked bag — hold luggage is always an extra.
The carry-on is listed for Econo, Member Exclusive, EconoFlex, Premium, PremiumFlex, Business and BusinessFlex — UltraBasic is not on that list and pays a checked-bag fee plus a service fee for anything that will not fit the sizer. Allowances apply only on flights operated by WestJet or WestJet Encore; on a partner's flight the partner's rules apply, decided one-way by whoever operates the first flight in each direction.
A bag packed to WestJet's free limit (41 × 33 × 15 cm, longest side first) is compared against every other airline's free allowance, rotating the bag where needed.
