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

Chairs do not recline. Finished the trip with an aching back.

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.

Boarding was odd. Gates switched and had to take a bus to the plane. Luggage got lost. Still waiting on one bag. Flight itself was very nice!

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

I have nothing but great things to say about the crew of the American Airlines flight from Madrid to Dallas. They were fantastic! I do, however, have some disregard for the flight attendant that was late in Dallas, causing us to further delay the boarding of our flight to Portland, and leading to the eventual cancellation of that flight. Because that crew-member was so late, we got caught-up in a weather-related ground stop, eventually causing our pilots to "time-out". So we couldn't get out of Dallas. We would have departed DFW on-time (and before the arrival of the thunderstorm) if not for the lateness of that crew member. The whole time the pilots couldn't tell us whether the flight would be cancelled, and that they couldn't get any information from the airline. By the time we knew the flight was cancelled, all of the flights for the following day were full. So, we didn't even get offered a viable option to get home. The American Airlines customer service desk at DFW was grossly under-staffed. And there were several people who waited in line for four-hours before being helped at that desk. We waited in line for almost 2-hours, until I was able to speak with a customer service agent on the phone (after being on-hold for over an hour). So, once we knew the information about how to get our bag in PDX, and that there weren't any options for flights the next day, we left the line & began searching for another way home. We eventually had to purchase a ticket home on a different airline, in order to get my wife to work on Monday. And we are pursuing a refund of that DFW-PDX leg of the journey. The good news is that the late flight attendant's hair was perfect. And she looked fantastic as she departed the airport & headed back home, while we all hunkered down to sleep in the terminal for the night.

Delayed and missed connections on leaving the states and returning Planes were old and small- very uncomfortable. Meals were good but very infrequent service for even water/drinks. No explanations for 3+ hour delay

One of the crew members hit me with the car and not even says anything

They need to start flying on time. We lost 2 days of our time because they delayed flight both ways.
