WestJet Personal Item Size
Exact personal item rules for WestJet, verified against the airline's own published policy on 2026-04-19.
Quick answer
Yes, a standard backpack, tote, or laptop bag fits as a personal item on WestJet as long as it measures under 16 x 13 x 6" (41 x 33 x 15 cm) and fits fully under the seat in front of you.
On Basic Economy fares, the personal item may be the ONLY bag you are allowed to bring on board without paying extra, so size matters.

Frequently asked questions
What is the WestJet personal item size limit?
WestJet allows a personal item up to 16 x 13 x 6" (41 x 33 x 15 cm). Must fit under the seat in front of you.
Does a backpack count as a personal item on WestJet?
Not always. A typical 18 x 13 x 8 inch backpack is larger than the WestJet published personal item limit of 16 x 13 x 6", so it may be treated as a carry-on. Slimmer laptop backpacks often still fit. Measure yours before flying.
Does WestJet weigh personal items?
Personal item weight is not published by WestJet and is rarely enforced at the gate for US domestic flights. On international routes, especially with codeshare partners, agents may weigh bags, so keep your personal item reasonable in weight.
What if my personal item is too big for WestJet?
If your bag exceeds 16 x 13 x 6", a gate agent can ask you to place it in the sizer. If it does not fit, you may need to pay a carry-on or checked bag fee. On Basic Economy fares, an oversized personal item is the most common cause of surprise fees.
Can I bring a personal item plus a carry-on on WestJet Basic Economy?
Often no. WestJet restricts Basic Economy passengers to a personal item only on many routes, with full-size carry-ons either banned or charged as a paid add-on. Read the fare rules at booking before you pack.
