Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

It was truly a horrible flight. We were delayed almost 2 hours. The seats were so tiny, my legs were hurting the entire flight. When i finally made it to Ireland i missed my connecting flight because we left Newark late. I will most likely never fly Aer Lingus again

Coming from the EU to the USA, Aer Lingus is a very good choice. You clear U.S. border control while still at the departure airport, so when you land in the States, you don’t need to go through the entry process again — very efficient and fast. In terms of comfort, Aer Lingus is better than the usual EU carriers like KLM, Lufthansa, or Air France, and also better than United. There’s more legroom, and the crew is helpful and kind. The food is average but slightly better than most airlines. Overall, the crew is definitely better than on American Airlines, though not quite at the level of Virgin.

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.
