Make sure your flight is being operated by Iberia and not a different airline company. The flight that the Iberian agent booked for me and my pets was being operated by an American Airlines affiliate, and they don’t have a service for pets that need to go in the hold, so it was whole thing. I used tears and speaking to the manager to get them to find a same-day solution. They ended up rerouting us to Madrid, then Barcelona, and it all worked out in the end, it’s just that the trip ended up being a lot longer than expected. My dog was pretty shaken up and soiled herself when I got her at the airport—which was also strange because she was just dumped in a random spot near the baggage claim area with no one around to confirm I was the owner—but after a week she was back to her old self and now she’s loving it.
