Stewardess was not attentive at all asked for a bottle of water never came by 15 minutes later I asked her she said that she forgot there was only 12 people in first class and two stewardess unacceptable I ordered the fish was the last person to order. They said that they did not have any had to have a different item pasta at the inside of it because I was diabetic. Worst experience I ever had will never travel this airline again.

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

Flight to get to Barcelona was cancelled and then the next flight was overbooked. Cancelled the entire trip and went elsewhere. Fighting with iberia to get my money back. Ill never book this carrier again!

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Difficulty to check in online, but well handled at the airport. Flight delay was unfortunate. Crew was adequate but not what we have usually experienced from BA. Seat was not comfortable.

Arrived on time. Great crew. Good food. Luggage delivered promptly

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

Boarding on the buses isn’t efficient. Overall, it was great.

I liked the comfort of the plane. It was unexpected from past experiences.

The app on phone and the online check in is not good, it would not give me the option of Spain or Madrid City in the drop down menu and I couldn't move forward with online check in.
