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

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

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

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

I was not admitted to the flight!!! i need a refund for this.

I was so grateful for the kindness of the crew. They made a long trip very pleasant. Food was delicious. Many movie options

We were very satisfied and would fly with Aer Lingus again in the future.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

- delayed because video screens not working - delayed getting a gate at DCA Just continued bad experience IAH to DCA.

The business class service was very good. The crew was helpful and the food was enjoyable. Boarding was well organized.

Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Flight was delayed almost an hour because the cleaning crew broke one of the bathroom doors.

When we boarded we were treated with care and it never stopped. Got towels before breakfast and after snacks was a lovely touch!

The flight crew was the worst I've experienced. If they worked for me, I would fire them immediately. They never smiled, they seemed angry and avoided passengers as much as possible. The food was not edible, and my luggage was lost. I will never fly United again!!!

Fought with Lufthansa was poor, seats are uncomfortable, food was bad and luggage did not arrive to IA

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

If other people in flight, followed instructions and were much cleaner.
