Awful customer service. What you are told 100% depends on who you talk to.

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

The check in and boarding process was smooth, and the flight was fine.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB 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.

I liked how they looked after couples by providing a row of 4 seats if available.

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

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Wifi is very frustrating - could not connect and therefore unable to work on the trip

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.

Food was good. Clean aircraft. But why do the airlines make the seats so narrow?! Your executives should have ride in a seat so restrictive for 11 hours and see how miserable it is! When.we got to MUC they changed my boarding gate 3 times for my next flight!!!!

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.

Boarding took a long time for a couple of flights. We arrived at our final destination an hour late. Others missed their connecting flight. We had no time to eat between flights. My checked in bag was delayed because it was in another flight. At least they gave us a voucher because of that. The staff was very kind.

The delay was not handled well and the offers to move flights and get travel credit was also not ideal.

The worst seat in any business class. Food are worst then economy class.

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!

Multiple delays and made us miss the connecting flight and lost our bags

Business class flight attendant was very good. But our flight was delayed two hours for a “mechanical” bathroom issue that literally took 5 minutes to fix. Our plane landed early from its previous flight but still waited for a mechanic to show up to fix an obvious minor issue for almost three hours. This caused us to miss our connecting flight. They put us up in a Days Inn that was 17 miles away from the airport that took a half hour of driving just to get to and this was at 11pm at night. Then when we finally got back on a plane after a full day delay they left our luggage back in the airport. This was an international flight, so no luggage or belongings after flying 8 hours to a different country. We will NEVER fly American Airlines again.

I was able to enlist on standby for an earlier flight, and eventually made it (last row). However, the experience was poor and felt unfair. On the standby list, I was ranked #2 (#1 had been cleared a seat). The person ranked as #3, who was also in the queue alongside me was given a seat much earlier - with group 4 boarding (a seat within the first 2 rows after business class). When inquired about why I was skipped-over on the priority list, the gate agent first paused (likely cuz she couldn't explain) - and then gave me the standard expectation that if a space opens up, she'll give me the seat. Despite my priority ranking being higher, I was unduly held-back, and could have missed the plane - unfairly giving advantage to someone else. Luckily one seat opened up; but given the unfair assignment of standby seat by gate-agent, this was a subpar boarding experience.

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

Do a bit better with n first class offer some real food and pillows

It was Christmas and the crew was awesome. And the passengers were patient.
