Very good- all went as planned. Flight was on time. Seating was a little sub , as always. Snacks and entertainment were basic. We arrived on time- no problems.

Very good- all went as planned. Flight was on time. Seating was a little sub , as always. Snacks and entertainment were basic. We arrived on time- no problems.

Everything was great, from the flight and crew to the seating and snacks.

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

There was an incredibly surly flight attendant that ruined the experience

Good but since we got in early we had to wait on runway for our gate. That was kind of a bummer but we still got in earlier than planned For entertainment I was watching a movie and getting close to the end of it with 15 min left but it kept jumping automatically to the next movie before finishing.

Delta seems to be getting worse. They are trying to take any comfort away from poorer people to make more money selling it to the rich. I paid for delta comfort and on my flight from Rome to jfk I had a tv that would go on and off automatically and literally no electrical outlets or usbs worked which was advertised in the price of the fare. The infotainment system wasn’t fully working. Luckily the movies worked and the plane was needing a lot of repairs. The jfk to Tampa flight they stuck me next to this really larger guy who was half in my seat and they should have made other accommodations for him because now you’re interfering with the fare class I paid for and act like I shouldn’t care because I didn’t pay for first class. I couldn’t even pull out my tray table because of this guy. The safety video tv screen you couldn’t even see it. It made me a little scared to fly delta anymore, because if these planes are this much in need of servicing, I have to wonder if the plane is going to make it to the destination.

Delayed departure, 30min. but arrived nearly on time. Crew was reassuring.

Connecting in Paris is always a wildcard, and this time was no different with the new EES system that people, including staff, don't really have a handle on. At least this connection didn't involve a bus, which has been a nightmare in the past. Boarding was a bit late, but once on the plane, flight was great. Very comfortable suites in business class. Service very good. Food was excellent. The Starlink WiFi was amazing. Worked well all the way from Paris to Atlanta.

First, off the bat, the Delta gate attendant was rude, inattentive and gave us an attitude when we asked for clarification of our seats for this rebooked flight as we missed our connecting flight due to the delay from Berlin. Flight attendants were all but friendly, rushed through for water refills so you couldn’t even catch them to request more water. Snacks were just OK. Headphones for the movies were so bad that with the airplane noise, the volume of the movie wouldn’t go up enough to even understand the voices. I had to turn on CC to even know what was being said.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

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.

Didn’t have requested food and seats could be more comfortable.

Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

Economy seats a bit small but other than that it was all good.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

Very efficient. Economy is what economy is. Wish it had been direct. Excellent setup in Newark for commuters and access to charging stations and wifi Flight could’ve had free wifi

Takeoff delayed 2 hrs. Boarded on time to find we were missing part of the flight crew. Then informed that they had loaded too much fuel. Spent 1 1/2 hrs sitting there burning off the excess, which included a couple of laps around the runway until we were light enough to fly! Ridiculous!

Flight from Munich to O’Hare was great but it was on Lufthansa, a UA partner. It had more legroom than United, seat slid forward to make reclining more comfortable, they offered free drinks. United offered none of this. Oh and the food was superior to United’s which honestly, sucked.

The WiFi went out an hour before the flight was due to land so I did not get my money's worth.

I have been flying united for a long time but now I’m done

It's not United, but TSA security at Terminal A in Newark is a disaster and seriously makes me consider switching to flying out of JFK. The touchless TSA pre-check had a line of over 50 people and the bag screening was so slow that it limited the flow of people through the facial recognition process. It is the only airport that I frequent that has this issue and makes me reconsider whether I should fly out of Newark given the wasted time and frustration it causes. As I said, it is not a United issue but will impact United if people choose to stop utilizing Newark airport because of the poor experience.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

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.
