I truely appreciate all services. I was highly impressed and will not hesitate to recommend United Airlines to friends and family. The AVML was perfect.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airport terminal was outdated, flight was on a small jet with no wifi

Essy to get on. The hostess gave very little pop, the plane was late getting in, and we are still waiting for our bags. This sucks. :/

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We boarded and buckled and then deplaned due to no pilot. Had to wait over 3 hours for a new pilot. Not weather related, just poor management.

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

I like the speed of boarding and deplaning and the fact that everything was on time. The crew (attendants) were probably quite new and did not begin the in cabin service until 30 min before landing even though there was little to no air turbulence for the last 1.5 hours of the flight. It made for a mad scramble at the end to get trash collected and carts stowed before touch down.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, so maybe there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

American Airlines “Randy” questioned why I needed preboarding and denied my request for same. Then Randy attempted to berate me when I boarded with my group. I was seated in an exit roll with a young man with a disability that exhibited difficulty controlling and settling himself. But Tandy questioned my disability. The flight was horrible. It was overpacked.

I have very bad experience with United because Vince two weeks that I did not receive my luggage yet

the blanket was great and pillow helped. really need a toothpick packed with meals

It was okay. Mothers with rowdy children should be invited to sit in front of them.

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

Well,I miss a flight to Stl with United,they send me to Stl with a different airline, but same day,which was great

NEVER TOOK THIS FLIGHT. LUFTHANSA CANCELED THIS FLIGHT WITHOUT ANY NOTICE. We were rerouted through Chicago on United airlines with a layover of five hours and then on American Airlines to St. Louis. The United club lounge in Chicago is good but there is no shower unlike Bangalore 080 lounge

At the gate I requested a change of seat to an aisle because of a medical issue, and I was graciously accommodated. Everyone was very pleasant and helpful.

Had to push staff to get good flight due to cancellation and delays for staff shortage

Tiny plane Had to gate check bags, a problem since we were flying back from an international vacation

OK. Needed more information on baggage details with different airlines and airport baggage pickup Also, it appeared they offered free WiFi on their info publications but none did.

Great until k found out they never got my check bags onto the plane.

It was pretty decent mostly cause I have leg room.

The first leg of our booked flight was severely delayed, and by the time I could get to an agent to see about re-booking, it was impossible to arrive in time to board for the final leg to Reykjavik. We were flown by American Airlines to Heathrow but didn't arrive in time to take the British Airways flight. BA only flies once a day to Reykjavik, so we had to purchase an absurdly expensive flight through Icelandair out of Gatwick to arrive in time for an excursion that started at 9 a.m. the next day. Our luggage got lost in the meantime and wasn't found for several days.

God food! Although some of the snacks were not to my taste. Nice amenities in premium economy made for a comfortable flight. The pilot was able to make up about half the time we were delayed in the ground (we were delayed over an hour before takeoff due to a shortage of tugs) Nice movie selection for entertainment. We were last to board the second leg of our flight due to.complications during transfer from the first flight of our trip, but did manage to board in time. We really enjoyed the video presentation for flight safety. Hilarious gets your attention! Really nice, sufficient accommodations for overhead storage, didn't seem crowded or jam packed. I enjoyed being able to track the flight on my monitor. I was disappointed that there wasn't free WiFi during the flight, I thought that was a complimentary service but you had to pay extra. It felt like we were nickled and dimed on that one.

That airplane is the most uncomfortable I’ve ever flown! Flight 267 LON-PDX Aug 10, 26 The middle armrests didn’t go up all the way. The aisle arm rest didn’t raise at all. The leg room area was compromised by a large metal box on both exterior seats. The headrests didn’t flatten. We got an email apologizing for no WiFi, but on the plane we’re told there would be WiFi. I never got it to connect. Pre-boarding support was great. Boarding was smooth. Crew was great. Food was DELICIOUS. A different plane would have resulted in a much better score.

Lovely attentive staff and even though take off was a tiny bit late, the pilot landed us early in PHX. Smooth easy journey and good touchdown.

This flight was OK, and about as good as a long-haul economy flight gets. The Good: * I was seated in a row with my family; * There was (just) enough space in the overhead bins for our luggage; * The cabin never got too hot; * The meal and beverage service was decent, and included all-metal cutlery; * The entertainment was good; * The cabin attendants were friendly and helpful. * Immigration control at JFK was a breeze -- all we had to do was get our photos taken, and we were through! Presumably this was because Madrid shared all our information with JFK in advance, but we were out of the airport within about 10 or 15 mins of getting off the plane, which is by far the fastest I have ever got out of JFK! The Bad: * We flew economy, so of course the seats were tiny and it was very cramped; * The seats were also hard -- I had a sore butt by the end, despite using the provided cushion; * The cabin got a bit too cold at one point (although I MUCH prefer this to cabins that are too hot), and Iberia also provided a blanket.

Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good

They ran out of earphones so my 3rd daughter couldn’t use the on board entertainment the entire flight. They also ran out of food choices (chicken or cheese) by the time they got to the last few rows, so my oldest daughter, wasn’t given a choice. Luckily she isn’t a vegetarian because they only had chicken left.
