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 17 airlines we track: Delta, American, United and Frontier allow more, while Air Canada allows only 8".

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.
