The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Everything was smooth and the meal was delicious. I really appreciated that Aer Lingus still offers complimentary beverages, food, luggage and headphones. It was nice that the main meal also featured some items typical to Ireland including the wheaten bread and Kerrygold butter. I generally found the flight a quite relaxing and enjoyable experience.

The seats are so close that you have 0 room to move. Not acceptable for an 11 hour flight.

Easy process you definitely need 3 hours to get on board from Fuminchino airport

Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

First time flying airline. Great experience. Clean plane, comfortable seating, great service.

They lost my bag so that is unfortunate.. still waiting for it

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

JetBlue is always consistent and great, the food is limited in selection, but at least you can grab as much as you want on snacks and drinks at the Blue Locker.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

For some reason, the seats on this flight seemed unusually uncomfortable. Speaking with friends who took another JetBlue flight later in the day, they brought up the same issue.

Wifi screens were great. Both flights were delayed, spending all day flying home and then getting home at 3am ruins the next day also.

I liked that 5 pound refreshment voucher was given for 1 hr delay. Staff were courteous and professional. I was expecting more for the 2nd meal (pizza). Usually for a long flight, the 2nd meal is something like eggs/sausage/potatoes/fruit/dessert.

The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.

More options on TV shows and movies and make it where if someone wants to choose their seats that it is an easy process. I wanted to choose our seats and never could do that! I even called and they told me I had to do it with agent at the airport. That was very inconvenient

We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

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!

WiFi didn’t work for me. as headphones didn’t work either.

Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!

entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.

The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.
