Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Great experience. Boarding was fast, staff were very nice and funny, everything at the seat worked well.

Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Flight attendants were great. Food mediocre. Bamboo utensils not Great especially if you have to cut something. Seating a bit crowded.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

The crew was the worst ive ever had in my life flying with United Airlines, letting another person move my bag without asking and then the staff saying would the floor be better after I kept begging saying dont move my bag it has fragile things inside. This incident truly makes me they favor other customers more and I dont want to worry about being on the tail end. Especially if they dont listen any input, no care for what I asked but accommodated those who are reckless and disturb others more...

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

United has been holding my money for a cancel on another ticket they wouldn’t let me fly for going on 5 months. Terrible service I wouldn’t choose to buy tickets or fly with united again. Very bad experience generally dishonorable and poor service .

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

OK overall. Flight was delayed Crew on flight was good

On time, only a little turbulence, very competent and caring attendants. Clear information.

Good experience. Flight was on time staff was pleasant. One of the airlines I would highly recommend

The flight was delayed 14 hours and communication was very poor. No one seemed to know what was happening and the gate agent was trying to help people for several flights. She was by herself trying to help 100s of people.

Domestic flights are good. Just stay away from international travel

Every time I leave from sti Dominican Republic, there is always a delay with a flight , causing a rush to make it to the next flight considering you have to go threw immigration

Flight left 2 hours late with no explanation as to the delay

I will NEVER fly with this clown show airline again. Idiots. All of them. Unprepared. Unfriendly. Miserable employees. NEVER. EVER. AGAIN

For whatever reason, I could not check in online. Kept getting the "It's not you it's us" message. Even when we tried the kiosk at the airport - same results. The check-in person had a very difficult time getting our boarding passes together despite the fact that we could show confirmation on the jetblue website. After a very long time we finally got boarding passes. The only other issue is, my vegetarian meal featured chicken.

The aircraft was fine, it’s was just the service. The flight got canceled several times and that was very inconvenient for my 69 years old mom.

My checked in luggage cost was $59, almost ticket price. The first 13 rows were empty, but fly attendant did not alow women with little boy change her middle sit, sweet boy was crying, I am so sorry for mother and passengers. At the end of the flight the cabin became impossible cold. Only good was timing of departure and early landing, but it suppose to be normal.

I tried to book a flight with Jet Blue. Your third party company hijacked my attempt with a website that looked like I was booking with Jet Blue. I realized it when I paid. I tried to cancel and was told by a man in India that there were no refunds. $735 stolen, Thanks Kayak!

Movie selection was nice and chicken with rice dinner was good. I did not like the pizza thing they served for breakfast/lunch. It was like a hot pocket but mostly bread. A small sandwich or cheese and cracker snack and fruit etc would have been much better. Also they did not announce trash pick up so a lot of trash was left by everyone when departing.

Too tight connection. Lufthansa staff pulled 12 of us out of passport control that had tight connections and took us about 1/3 mile AWAY from our gates and put us in another slow, long line. Needless to say all of us missed our flights and the Customer “Service” staff was rude and not helpful at all. Was rebooked from a direct flight to one w a 6hr layover. Asked about an other option that was on my app and was told to book it myself online (which would be $300 extra pp!!). Got rebooked again w a tight connection which was also missed. Rebooked into middle seats that didn’t recline for 9 hr flight!! No compensation (and we paid for seats!) Ended up taking 26hrs to get home from Europe to North Carolina! No longer a fan of Lufthansa—2nd time having these kind of issues w them!

Paid $35 for wifi but wifi didn’t work. Stressful dealing with work mess and no service. Otherwise normal

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

Our screen kept turning off ...3 times...had to get crew attention to turn it on again

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

Flight was delayed by several hours and then cancelled due to weather. But Staff was very helpful getting me on a different flight. United should offer food coupons and tooth brush and paste for stranded passengers

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!
