Food was terrible, tasteless. I ordered ovo lacto special menu in business class and got vegan tasteless food instead. Really disappointing.

Food was terrible, tasteless. I ordered ovo lacto special menu in business class and got vegan tasteless food instead. Really disappointing.

From boarding, to attention in flight, I couldn’t fault it.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.
