If you’re comparing WestJet with other North American carriers, you’ll notice some clear differences.

On the stricter end, Spirit Airlines baggage rules are far less flexible, especially for basic fares.
Carry-On Weight Limit & Baggage Allowance
WestJet does not specify an exact weight limit for carry-on baggage.
Instead, the rule is simple:
- Your bag must be light enough for you to lift into the overhead bin without assistance
If you can’t lift it yourself, it may be checked in.
Standard allowance:
- 1 carry-on bag + 1 personal item
UltraBasic fare:
- Only 1 personal item allowed
- Carry-on bags are not permitted, unless:
- You’re flying to/from Europe or Asia
- Or you’ve purchased Extended Comfort for all flights in a direction
Personal Item Size & Carry-On Bag Allowance
Your personal item must:
- Fit under the seat in front of you
- Stay within 41 x 15 x 33 cm
Common examples:
- Laptop
- Small backpack
- Purse
- Camera bag
Important note:
- A pet kennel counts as your personal item
Carry-On Size Restrictions & Rules
WestJet includes several important baggage restrictions beyond just dimensions:
- Bags must fit in the sizing device
- Must be stored correctly:
- Carry-on → overhead bin
- Personal item → under the seat
- Must pass airport security screening
Liquids like shampoo, perfume, toothpaste, and moisturizers are only allowed in limited amounts, based on rules set by the Canadian Air Transport Security Authority.
Also:
- Items must be allowed in your destination country
- WestJet is not responsible for items confiscated at security or customs
Unapproved devices (like knee defenders or seat attachments) are not permitted onboard.
If you’re unsure what actually qualifies as a carry-on, it helps to understand the basics before packing. This guide on what counts as carry-on luggage breaks it down clearly, while carry-on vs personal item differences explains exactly how airlines separate the two. You can also check carry-on weight limits across airlines to see how WestJet compares.
Maximum Carry-On Size Allowed by WestJet
The maximum permitted size for a carry-on bag is:
- 56 cm x 23 cm x 36 cm (22 x 9 x 14 inches)
Anything exceeding these dimensions will be treated as checked baggage.
How Strict Is WestJet With Carry-On Size?
From real traveler experience:
- Staff may ask you to place your bag in a sizing bin, especially on busy flights
- UltraBasic passengers are checked more carefully
- Bags that look oversized are often flagged at the gate
Another important detail:
- On WestJet Encore aircraft, overhead space is limited
- Even compliant bags may be checked before boarding
Carry-On Rules for Domestic vs International Flights
In most cases, the carry-on size and allowance stay the same across routes.
However:
- UltraBasic passengers
- No carry-on on domestic/U.S. routes
- Carry-on allowed on Europe and Asia routes
Also, if your journey involves a partner airline, their baggage rules may apply. Fees are typically charged by the first airline operating each direction of travel.
For real travel scenarios, especially international trips, baggage rules can vary more than you expect. While WestJet follows consistent policies, it’s still smart to review carry-on liquid size restrictions before heading to the airport. You can also compare with European carriers like Ryanair carry-on rules, which are known for stricter enforcement.
What Happens If Your Carry-On Exceeds Size or Weight Limits?
If your bag doesn’t meet the allowed size:
- It will be checked at the gate
- You’ll need to pay a checked baggage fee
- UltraBasic passengers may also pay a service fee
Payment rules:
- In Canada → credit and debit cards accepted
- Outside Canada → credit cards only
Carry-On Allowance by Fare Class (Economy vs Business)
Most fares (Econo, Premium, Business):
- 1 carry-on bag
- 1 personal item
UltraBasic fare:
- 1 personal item only
- Carry-on not allowed (unless exception applies)

WestJet provides specific guidance for storing your bags onboard:
- Place roller bags in overhead bins, wheels first and on their side
- Store laptop bags, purses, and smaller items under the seat
