Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

Gate agent in Atlanta refused to let me take my carry-on on the plane even though I met weight and size requirements and the plane was half empty. My ticket clearly stated that I was entitled to one carry-on and one personal item. Will not fly this airline again.

Flee premium economy. Very comfortable absolutely a better seat more recline, wider, and more legroom. Flew Business, which was lie flat comfortable with decent food. In P E Basically the screens audio hardly works and the selection although 90% in English is very limited. Wi-Fi did not work both ways across the Atlantic. It was “broken“ very efficient operation. The app was great. Notification is fine. It was just the entertainment and the food in premium economy was lousy airline food. But yes, I would fly them again in PE or business if they were going my way.

not good missed my connection SAS did not leave me anywhere near enough time to make my connection. Ended up adding about 10 hours to my travel day

I travelled business class with my spouse from ATL to Helsinki and back from Riga to ATL. The seating was not very comfortable. Bread crumbs and left over disposable items from previous passengers were not picked up. The cabin was extremely noisy as the crew keep talking and laughing all night long making it difficult to relax or let alone sleep. Crew must make sure to keep the cabin as quiet as possible. The seating should add a privacy features such as curtain or something. Food choices are limited and average at best. I travel very frequently but this was my first time with SAS. I would try to avoid travelling with SAS in future and would not recommend it to my friends or family. My return flight Aug. 9th was cancelled for no specific given reason or explanation. The new flight on Aug 10th was delayed by 45 mins even though it took off on time. Sorry, if you are disappointed to read my survey but I have to speak the truth. Nayyer Islam, MD

From my last trip nothing except for the luggage fee

I loved the food. The veggie option was delicious. I also appreciate the sense of sustainability with Airline's choice of packaging. Hosteses were super friendly and courtous. I also appreciate that checked luggage was included with the airfare. The entertainment portal could see some improvements. The touch screen responsiveness in Solitaire game was poor and it doesn't seem to be hardware related as other screen functions were just fine. It was hard to move cards between piles and system skipped cards from the deck. Also, there was no option for winnable vs random draw. Sudoku was cumbersome regarding touch screen, too. In addition, the difference between medium and difficult levels in Sudoku was huge. Medium was actually too easy.

This was my return flight and it was 100% different than my out bound. Better seats and great food for sure. As i was disappointed last time but this time they made up for it

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.

First time flying with UA and it was a great experience. Thank you

Staff on board was excellent. Positive upbeat helpful- like it used to be.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

Didn't make it dir to delays - no support from United staff

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

Textbook great flight. On-time departure and arrival, clean plane, good food, friendly flight attendants. Checked baggage delivered promptly.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

The crew should demonstrate flexibility by moving a screaming infant to its own seat with 1 parent

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

Great experience. Flight was on time and reached destination on time

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Did not fly HOU to SAT as flight was cancelled.

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.

Very comfortable flight and simple and directed one way and back. Amazing price.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

The flight was an hour late leaving Heathrow. The food was mediocre. When we got to Austin, my husband’s luggage was missing. He filled out information at baggage claim. We are waiting to hear something. His name is Henry Jacob Braunig.
