WestJet is changing its carry-on baggage policy starting May 6, 2025, to match the size limits used by most major North American airlines. The new maximum dimensions will be 22 inches tall, 14 inches wide, and 9 inches deep (56 cm x 36 cm x 22 cm), including wheels and handles. This replaces the previous standard of 21” x 15” x 9”, adding an inch in height while slightly reducing width—a change designed to align with luggage sold by major retailers and make travel easier for passengers using multiple airlines.
The update comes after years of feedback from passengers and crew about the confusion caused by different baggage size rules across airlines. WestJet hopes the new dimensions will simplify boarding, make better use of overhead bin space, and reduce delays caused by gate-checking bags. The airline has confirmed that bags meeting Delta Air Lines’ current size limits will automatically comply with WestJet’s new policy, giving frequent flyers peace of mind.
Passengers have until May 6 to adjust to the changes. Both old and new sizes will be accepted during this transition period. To help travelers prepare, WestJet is installing updated baggage sizing templates at all airports it serves by March 13. After the deadline, stricter enforcement will ensure smoother operations for everyone.
WestJet’s Colleen Tynan, Vice President of Experience Management, shared her thoughts on the change: “Standardizing carry-on sizes means fewer conflicts at boarding and more space for everyone—a win for both guests and crew.”
For stress-free summer travel, measure your bags carefully (including handles and wheels) and check your luggage against the updated rules. This move reflects a growing trend among airlines to adopt consistent policies that improve efficiency without sacrificing passenger convenience.
