Check in wasn’t the best since i had to go to additional security check. Waste of your and my time but i do understand. Worst part of the journey was broken seat, it was hard to sit on it for 7 hours. Someone need to check on cushions and replace them as i felt i was sitting on metal rod all the way. Food and entertainment was solid and crew was good.

Check in wasn’t the best since i had to go to additional security check. Waste of your and my time but i do understand. Worst part of the journey was broken seat, it was hard to sit on it for 7 hours. Someone need to check on cushions and replace them as i felt i was sitting on metal rod all the way. Food and entertainment was solid and crew was good.

The staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

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.

United staff were very communicative, the new starlink Wifi is amazing as I was able to work easily.

Seats are made for children. An 8 hour flight with tiny seats is more like a cattle car. Lost bags at Rome airport caused a 7 hour delay.

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

Worst boarding experience, flight extremely delayed causing super tight connect and deplaning was a disaster as ppl were pushing and shoving to get off. Then after flying over 8 hours had to get off a job to next flight. Limited beverage service in Business class (water or white wine) no food. The plane was very cold (temperature) so uncomfortable

- 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.

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