Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

The flight was smooth, the pilot kept us informed about delays and we arrived more of less on time

The flight was flawless and we even arrived between 20 and 25 minutes early!

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

Very crowded flight but what can you expect these days?? Crew was accommodating.

The seats in economy were appeared to be quite thin and lack sufficient cushioning to be comfortable. Perhaps it was my seating position but the plane seemed notably load.

The entertainment package was vast and the selections were very current. Keep updating it was great.

The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.

It was budget airline Veuling, even though we booked Iberia.

The staff was very nice and helpful. Some of the best crew I have met.

Bad experience. The seat room are very tight. The food is not good and the breakfast has no hot drink.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

Great : The crew was awesome ♥️ To improve : - The rice in the "Rice with chicken" was rather s kind of rice pudding, not good at all - No power outlet to charge your phone. 😒

It was a good flight overall. Nothing to add. Keep it up!

Excellent. Thanks to United Star Alliance, since economy was overbooked, I’m grateful to have been upgraded to Business Class.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

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

Disaster. Downgraded. Zero apology. No effort or coordination between gate and crew. Awful seat blocked by door emergency slide box. Iberia is a mess. App never works. Avoid this airline.
