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.

We departed late but made up most of the time in flight. Our ticket was pure economy, so it wasn’t anything fancy; however, I heard that we arrived in Madrid at the exact same time that First Class passengers arrived! Overall, our experience was similar to what we had on other American Airlines transatlantic flights - good value at a reasonable price. We were even able to get our carry-on baggage onto the plane without needing to gate check it.

Flight was OK. Waiting for luggage in Madrid for 55 minutes, unacceptable
