Check my bag for WestJetThe three baggage types, explained
Airlines split what you travel with into three allowances. Each has its own size and weight limit, and the one you exceed decides what you pay.
The small bag that goes under the seat in front of you — handbag, laptop bag or small backpack. Usually free and rarely weighed.
The wheeled case you take into the cabin and store in the overhead bin. Sized at the gate, and weighed by many airlines.
The large suitcase you hand over at the desk and collect at your destination. Charged by bag, with strict weight limits.
Frequently Asked Questions
Is a cabin bag free on WestJet?
Not on every fare. The cheapest option (UltraBasic) includes only a small bag up to 41 × 33 × 15 cm (16.1 × 13 × 5.9 in) that fits under the seat. A cabin bag up to 56 × 36 × 23 cm (22 × 14.2 × 9.1 in) comes with Econo and above.
What happens if my bag doesn't fit WestJet's sizer?
Staff can send it to the hold at the gate and charge for it, and a gate charge is usually far more than adding the bag online before you fly. The current amounts are on WestJet's own fees page. WestJet baggage fees
Can I bring a personal item in addition to my WestJet cabin bag?
Yes. Besides the cabin bag you can bring one personal item up to 41 × 33 × 15 cm (16.1 × 13 × 5.9 in), such as a handbag, laptop bag or small backpack, stowed under the seat in front of you.
