Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

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

The seat when "flat" was not flat and pad was too thin to cover it.

Seat comfort was poor (no lumbar or lower back support).

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

Aging planer and NO wifi on a 14 hour day flight. Unless you are retired or don't need to work or be in touch with the world... The lack of Wifif really ruined the flight. And the old plane - really showing it's age, wasn't great

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.
