WestJet carry-on size: Here’s what travellers need to know about the baggage policy change — and when it will take effect

WestJet, Canada’s second-largest airline, has announced a significant change to its carry-on baggage policy, aiming to enhance the travel experience by aligning with common international standards.

Effective May 6, 2025, the airline will implement new maximum dimensions for carry-on luggage, a move expected to streamline boarding processes and optimize overhead bin space.

Details of the Policy Change

The new carry-on size limits are set at 22 inches x 14 inches x 9 inches (56 cm x 36 cm x 22 cm), including wheels and handles.

This adjustment replaces the previous allowance of 21 inches x 15 inches x 9 inches, effectively adding an inch to the height while reducing the width by the same measure.

This change aligns WestJet’s baggage policy with those of other major North American carriers, including its partner, Delta Air Lines.

According to Colleen Tynan, WestJet’s Vice President of Experience Management, this update is anticipated to “help streamline check-in and boarding times by eliminating the inconsistency between WestJet and several other carriers.

” The standardization is expected to ensure more bags fit on more flights, positively impacting the overall onboard experience.

Implementation Timeline

To facilitate a smooth transition, WestJet will begin deploying new baggage sizing devices across all airports it services starting March 13, 2025.

Both the current and new baggage sizes will be accepted until the new dimensions officially take effect on May 6, 2025.

Rationale Behind the Change

This policy shift comes after years of WestJet operating with unique baggage dimensions that differed from other airlines.

Feedback from both guests and employees highlighted the need to maximize storage capacity across the airline’s various aircraft, leading to this decision.

The new sizing is also designed to improve cabin comfort and enhance the functionality of overhead bins, especially on full flights.

Impact on Travelers

For travelers, this change means that carry-on luggage compliant with the new dimensions will more likely fit into the overhead bins, reducing the need for gate-checking bags.

This alignment with international standards simplifies packing decisions, especially for those connecting with other airlines that have similar baggage policies.

Comparison with Other Airlines

WestJet’s updated carry-on dimensions are now consistent with many major carriers.

For instance, Air Canada’s allowance is 21.5 inches x 15.5 inches x 9 inches, while Delta Air Lines permits 22 inches x 14 inches x 9 inches.

This harmonization facilitates smoother connections and reduces confusion among passengers regarding baggage allowances.

Additional Considerations

It’s important to note that this change pertains specifically to carry-on baggage dimensions. WestJet’s other baggage policies, such as those concerning checked luggage and personal items, remain unchanged.

Passengers are encouraged to review the airline’s official guidelines before traveling to ensure compliance and avoid potential fees or inconveniences.

Conclusion

WestJet’s decision to adjust its carry-on baggage dimensions reflects a commitment to enhancing passenger experience by aligning with international standards.

This change is expected to streamline boarding processes, optimize cabin space, and provide greater consistency for travelers.

As the implementation date approaches, passengers should take note of the new dimensions to ensure a seamless travel experience.
