Really like the idea experience on this airline I will use again

The food on the flight was of marginal quality. Small bits of chicken, instant mashed potatoes and some carrots. The rolls were very dry, nearly inedible. The seats were quite small and didn’t allow for any shifting of position during the flight. There was limited leg room.0

We liked the flight but while we purchased an aisle seat, our seats had a different configuration on this flight. A fellow passenger suggested that the airplane had been changed. Too bad we were not informed and had no chance to modify our seat preferences. We were stuck in the window and middle seats with no chance to walk around and go to the bathroom without disturbing our sleeping fellow passenger.

Moved the flight an hour later, were not reliable about confirmation, website didn't work, no gate information, boarding was a mad house. Flight itself was fine and short. Organization needs work.

Not having to check carry on bags when plane wasn’t full. (The told us it was)

The connection required us to travel from terminal A to terminal E with very little time in between flights. While waiting in line, we were called to the service desk to provide our passports. We provided our passports at time of check in, assuming that American Airlines doesn’t communicate well with Iberia, this was a headache.

First flight was 5.5 hours delayed, the notification came within 2 hours of the flight (bags already checked in). connection missed- no one working on getting us on an alternate flight, knowing where our luggage will be. It was chaos figuring out how to get to our final destination. Customer service throwing us into nowhere on the phone- all while we have 2 small kids on us. It will take the whole vacation to recover from this experience. I am scared how the return flight will go in August. Check-in staff (not sure if they are airport hires or iberia hires- beyond rude, especially in Madrid.) On-plane staff, food and entertainment were good.

When I bought the ticket, right away I got a problem, I had to cancel. Unfortunately never ever I will use kayak or Iberia again. When trying to cancel kayak told me to talk directly with the airline, the airline talked to me through whatsap and told me to deal through kayak. Both of u never took responsibility in helping me out. You kayak did not want to deal with me. I called my credit card and now we r disputing the charge bc u have a pathetic customer service.

I didn't expect food on this flight but they give us breakfast, they also check in our hand baggage for free
