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. 1 of the 15 carriers we track clears that published limit.
The Sherpa Original Deluxe (Small) is the one that clears it, with 0.6" to spare on its tightest dimension. Swiss International's 9.1" height ceiling sits mid-pack among the 58 airlines we track (shared with Austrian, Brussels, ITA, Lufthansa, SAS Scandinavian, Turkish): Aegean, Air France, Air Transat and Alaska allow more, while EL AL Israel allows only 7".

How to confirm your actual under-seat space
Swiss International Air Lines'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 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.
