WestJet to Change Carry-On Sizing to Align with Other Carriers
by Bruce Parkinson
WestJet had a strong on-time performance in September.
Effective May 6, 2025, WestJet will change its maximum carry-on baggage sizing to align with common international cabin baggage dimensions adopted by other North American carriers and luggage manufacturers, including partner Delta Air Lines.
The new size maximums (22” x 14” x 9”) account for wheels and handles, which WS says will offer peace of mind around what easily fits into the overhead bins on board WestJet’s aircraft.
WestJet is adding an inch of height to accepted dimensions, and reducing an inch in width from the existing limits (21” x 15” x 9”). The airline says this will increase overall stowage capacity and improve cabin comfort and bin functionality.
“We expect this change will help streamline check-in and boarding times by eliminating the inconsistency between WestJet and several other carriers,” says Colleen Tynan, Vice President of Experience Management.
“Introducing a new standard size ensures more bags fit on more flights, so we expect this to have a big impact on the overall experience on board.”
The decision to adopt the new carry-on baggage size comes after WestJet operated for years with a size that was unique to airline.
“We’ve heard feedback from WestJet’s guests and employees around maximizing storage capacity across the airline’s various aircraft, which each have bin capacity variances. This includes Sunwing aircraft scheduled to be added to WestJet’s fleet this spring,” WestJet said in a statement.New WestJet baggage sizing devices will be delivered by March 13 to all airports where WestJet has service. To offer guests time to adjust to the new carry-on baggage dimensions, WestJet will continue to accept both the current and new maximum baggage sizing until the new maximum officially takes effect on May 6.
