Iberia Express, Iberia’s low-cost subsidiary based in Spain, is one of the airlines that accepts dogs both in the cabin and in the hold, under conditions. Weight limits, fees, restricted breeds and booking: here is everything you need to know before you reserve.

In the cabin

Iberia Express accepts a dog in the cabin if its weight, carrier included, does not exceed 8 kg (18 lb). The carrier must be soft-sided and fit under the seat in front of you.

Airline conditions: dog + carrier max 8 kg (18 lb); brachycephalic breeds in the cabin only; fee not confirmed.

In the hold

Above the cabin limit, your dog travels in a pressurized, heated hold, inside an IATA-compliant crate.

Airline conditions: hold (checked baggage); brachycephalic breeds excluded from the hold.

Brachycephalic breeds

Like most airlines, Iberia Express applies restrictions to flat-faced breeds (bulldogs, pugs, boxers, etc.), which are generally banned from the hold because of the respiratory risk. If your dog is brachycephalic, choose the cabin whenever its weight allows, and confirm the rule before booking.

How to book

Pet spots on board are limited: book as early as possible.

  1. Buy your ticket, then contact Iberia Express to add your dog to the booking.
  2. Prepare the health documents (identification, rabies vaccination, pet passport or health certificate, sometimes a rabies titer test) — see our guide to international travel with a dog.
  3. Choose the right container: an approved soft carrier (cabin) or an IATA crate (hold). Size it with our IATA crate calculator.
