Viva Aerobus in-cabin pet policy — and the carriers that fit
Viva Aerobus allows small pets in the cabin in a carrier up to 17.3 × 13.8 × 8.3 in, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. Viva Aerobus does not publish a cabin-pet fee on its own policy page. 0 of the 15 carriers we track clear that published limit.
That means no carrier on our list clears it outright — the closest is the Sherpa Original Deluxe (Small) (flexes — 0.2" over), with 2 others in the same range. Measure yours and expect an agent to check it. Viva Aerobus's 8.3" height ceiling sits mid-pack among the 77 airlines we track (shared with Vueling): Aegean, Air Europa, Air France and Air Transat allow more, while EL AL Israel allows only 7".

Measure the outside of your carrier (bulges included) and enter it below. The check uses Viva Aerobus’s published 17.3 × 13.8 × 8.3 in limit — height is checked strictly, the footprint may rotate.

This table ranks by Viva Aerobus’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
Viva Aerobus'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 Viva Aerobus to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
