We liked the flight but while we purchased an aisle seat, our seats had a different configuration on this flight. A fellow passenger suggested that the airplane had been changed. Too bad we were not informed and had no chance to modify our seat preferences. We were stuck in the window and middle seats with no chance to walk around and go to the bathroom without disturbing our sleeping fellow passenger.

Boarding an international flight via several sets of stairs and shuttle busses to the tarmac even when multiple jet-bridges were empty at Madrid airport (the hub for Iberia) was not pleasant. I was fine, but a lot of elderly folks and families with kids were struggling. A bad way to start a flight. Business class seats were nice, although not cleaned well from the prior flight.

This was a short flight. We sat in business class so we we were served a warm meal, which was nice. The flight attendants were very attentive, professional, and kind.

The flight was great; I don't see any area of improvement.

The crew were not very personable. The crew did not serve tea or coffee. The bathroom was not kept clean. Two out of the 5 toilets in the cabin weren't working.

Delayed first flight Geneva Madrid.. We didn’t miss our 2nd flight only because the 2nd flight Madrid Dallas was 1h delayed. However we did end up missing the 3rd leg Dallas Austin. Luggage didn’t show up in Dallas. So we re missing 2 suit cases. Customer service sent us to a hotel in Dallas. Only one room booked for 5!! Pretty bad experience overall. I won’t book a flight on Iberia in the future

Crew was excellent, great customer service, checked luggage took 1 hour and a half to come out at the baggage claim, the only negative thing about the flight.

Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again

People point to America as the model of late stage capitalism. My friends, airlines in america at least give you WiFi, and they haven’t quite smashed people into cardboard tv dinner trays yet. Iberia has mastered the tv dinner seat and WiFi is 20 euros. Be serious yall.
