Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

Excellent crew, food and service. Boarding via bus is always a pain but overall really good

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.
