If you are searching for a Naples to Barcelona flight with a dog in cabin, start with the checks that actually decide whether the trip can work: airline policy, total weight with carrier and pet space availability.
Quick answer
The Naples - Barcelona route can work for a small dog in cabin when the operating airline accepts pets on that flight and the carrier fits its limits. Passenger seat availability is not the same as pet availability.
Checklist for this route
- Airports. Search options from NAP to BCN and confirm the airline allows dogs in cabin.
- Total weight. The limit often includes the dog plus the carrier.
- Carrier. It must fit the airline and aircraft under-seat rules.
- EU documents. For Italy-Spain flights, check microchip, pet passport and valid rabies vaccination.
