Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

Flight was fine, but not having WiFi was a major negative

It was the most un-special flight experience in my life.

Not good. One of my luggage is missing. And until now they can’t find it

Dloght delayed by 2.5 hrs . Common theme in my last four american floghts

The flight was fine. It's the satellite terminal that supports American eagle flights is what sucks. There is only one food option and everything there is way overpriced. I mean I know it's airport pricing, but it's even crazier than that. I bought a sandwich in a plastic container for $18.

This was a horrible experience. I’ve experienced several delays at this point and still not home. I was supposed to be home by 8:30 last night and here I sit at 7 am on a plane STILL unable to go home because of American Airlines.
