It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

Good food & refreshment. The seats and entrainment screens are modern compared to others. The staff though pleasant serve and attend to passengers based on nationality. Some get served first others last regardless of their seating positions.

It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.

The flight was on time and arrived early. The crew were friendly and helpful.

My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

While I didn’t watch much tv I would have liked a few more options of TV series from Apple TV or hbo max ..

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Nothing to write home about, average flight experience. Seats were spacious enough, crew friendly enough. Loved the AA entertainment/wifi service.

Kayak was among the missing. There was not the usual advice regarding next gate after arriving in Dallas. No communication after the reminder to check in before the Moline flight. What happened?

Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.

Late flight Delays Poor service Poor staff Worst airline ever

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Awful it always is unfortunately is the only way to fly direct to london

I travelled in business class and was disappointed by lack of service, curt and borderline rude time of the crew and to top it off, all of my luggage was delayed. It was like pulling teeth to even report the missing luggage and recover it the next day from the airport.

Plane was extremely delayed, but not all of it was BA fault (some was). Worst part was lack of room - this had as much space as an Allegiant flight. I thought transatlantic usually gave you an extra inch or two, but not this one. Entertainment system sporadically worked and didn’t have great options. Overhead bins are old and tiny, not as good as aunties new planes.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.
