Porter : check your cabin bag’s size
Basic does not mean the same allowance on every route. The fee page distinguishes Canada, US and sun destinations from transatlantic routes.

Check my bagReference limits
Sides sorted longest to shortest; bag orientation is taken into account. Compare using the unit you measured your bag in.
| Bag type | All three outside dimensions | Weight |
|---|---|---|
| Cabin bag | 55 × 40 × 23 cm21.5 × 15.5 × 9 in | 9 kg / 20 lb per item |
| Personal item | 43 × 33 × 16 cm17 × 13 × 6 in | 9 kg / 20 lb per item |
These limits apply to each outside dimension. Their sum does not replace the individual limits. The checker accounts for bag orientation.
What your fare changes
Physical size and ticket allowance are separate questions. Choose the exact fare. If you do not know it yet, compare the dimensions while leaving the ticket allowance unresolved.
- Basic normally includes a personal item only on Canada, US and sun routes.
- Basic to Europe/Africa and Standard outside Canada/Europe/Africa: the fees pages and tariffs do not agree. Confirm cabin-bag inclusion in your booking.
- The three tariffs currently linked by Porter were read: domestic, transborder and international. They confirm 9 kg / 20 lb per item.
- A purchased Basic Express add-on can include a cabin bag. The cited tariff sets a 9 kg weight limit per item.
Worked examples
These examples illustrate the reference rules. Open a check to see the bag and ticket separately, with the applicable limitations.
Basic within Canada, even with a light bag
A 54 × 39 × 22 cm suitcase weighing 8 kg meets both limits in this example. Basic normally excludes that suitcase on the selected domestic route. A Basic Express add-on must actually appear in the booking.
Check this example ↗Basic to Europe: check the booking
This bag meets the size and 9 kg weight limits. For Basic to Europe, Porter’s documents do not give the same cabin-bag inclusion answer. Check that it appears in your booking before travelling.
Check this example ↗Standard, but 100 g over
A 9.1 kg suitcase exceeds the 9 kg ceiling even when every dimension fits and Standard includes this bag category. Weight remains a separate requirement.
Check this example ↗Before measuring
Yes. Measure the bag packed and closed at its outermost points. Bulging pockets and protruding wheels count too. The calculator uses the dimensions you enter. Potential compression is not permission: measure the bag as you will carry it and check the airline’s sizer.
No. The physical sizer, applicable ticket rules and onboard space still matter. An airline may require gate-checking even when the dimensions fit.
