the seats were bad and uncomfortable and the food was not tasty.

Delayed. Mismanagement of gate lines. Passengers arguing with eachother as a result of lack of organization by airline. Avoid this airline.

Because the plane was delayed from Madrid to LAX, we missed our connecting flight to Malaga. Iberia offered to book us a hotel room but I needed to be in Malaga that evening. I ended up buying train tickets to Malaga from Madrid. I also feel Iberia should compensate me for the cost of the train tickets because they didn't meet their travel obligation.

Terrible. Won’t fly again. Boarding was an issue. Took TWO hours to “find” my confirmed reservation. Crew at desk was super rude and unconcerned. Was not escorted through despite delay on their end. Almost missed fight and luggage arrived one day late…. Which I had to pick up by cab or wait even longer (not reimbursed).

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.

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.

Bag misplaced. Iberia claims bag has been forwarded. But AirTag shows that the bag is still in Madrid.

Great flight, short and good attention. Didn't took any food so can't say thing about it

My baggage did not arrive, missed connection, service representative was not helpful.

Outstanding. plane was a bit dated but safe and clean
