Swiss International Air Lines in-cabin pet policy — and the carriers that fit
Swiss International Air Lines allows small pets in the cabin in a carrier up to 21.7 × 15.7 × 9.1 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. In-cabin fee: Route-dependent, charged as excess baggage. SWISS's filed tariff (Rule 116, PETC max 8 kg) lists CHF/USD 60 / EUR 50 / CAD 75 domestic. 2 of the 15 carriers we track clear that published limit.
The Sherpa Original Deluxe (Small) leaves the most room — 0.6" on its tightest dimension, against just 0.1" for the Mr. Peanut's Gold Series Mini (Low-Profile). Swiss International's 9.1" height ceiling sits mid-pack among the 77 airlines we track (shared with airBaltic, Austrian, Brussels, Discover, Edelweiss, Eurowings, ITA, Lufthansa, SAS Scandinavian, Turkish): Aegean, Air Europa, Air France and Air Transat allow more, while EL AL Israel allows only 7".

This table ranks by Swiss International Air Lines’s size limit — not by your pet. The weight under each carrier is what that size is rated to hold. A bag can clear the airline and still be the wrong size for the animal, which is the most common reason one goes back — measure your pet first →

How to confirm your actual under-seat space
Swiss International Air Lines's number is its published maximum, not a guarantee 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 exit rows — bulkheads have no under-seat storage and most airlines ban pets there — and check this airline's seat rules above.
- Call Swiss International Air Lines to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
