Porter Airlines in-cabin pet policy — and the carriers that fit
Porter Airlines allows small pets in the cabin in a carrier up to 21.5 × 15.5 × 10.5 in, soft-sided, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. The in-cabin fee is $50–$57.50 per direction ($50.00 CAD/USD plus applicable taxes) · non-refundable. 6 of the 15 carriers we track clear that published limit.
The Sherpa Original Deluxe (Small) leaves the most room — 2" on its tightest dimension, while the Sherpa Original Deluxe (Medium) only just squeaks in with nothing to spare. Porter's 10.5" height ceiling sits mid-pack among the 58 airlines we track: Allegiant, American, Avelo and Breeze allow more, while EL AL Israel allows only 7".

How to confirm your actual under-seat space
Porter Airlines's number is a fleet-wide recommendation, not a promise for your exact seat. Before you buy or fly:
- Check which aircraft operates your flight (in your booking or on a seat-map site).
- Avoid bulkhead and some window seats — they have less (or no) under-seat storage.
- Call Porter Airlines to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
