Can you please process refund. Mum died and dad went to Pakistan to bury her after cancelling flight.

Short flight so no entertainment, turbulence so no food service - overall flight as expected

All was good, the only thing was it didn't run on time.

Great meal. Best seats ever! They need to teach other airlines how to do that.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

Couldn’t request a vegan meal somehow but I noticed other people getting them

United flight from SFO to PDX was cancelled. I will ask for a refund. Had to book on Alaska

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

The international flight from Sydney to Dallas had great food. I have travelled a lot over the years and this has been the most memorable in my experience so far.

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.) Lounge was crowded

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.)

Initial flight was cancelled so moved to an alternative flight. As a result, stuck in a middle seat. Flight then place in holding pattern prior to landing resulting in a very late trip home.

There was nothing I didn’t like, prices a little lower would help

Flight delay was informed at the last minute. Food quality is not up to Qantas standard I was unable to book an online boarding pass on any of my 6 flights.

Rescheduled after ticket purchased and issued, not 2 or 3 times and not a fourth but by 5 times, by Qantas, that's right, 5 changes! Forcing an overnight stay in Chile and need for visa. Qantas can no longer provide basic services as a national or international service provider. Professionalism is extinct and the provider needs to be mentored and educated in perfecting who to operate as an airline. Qantas is the spirit of Australian dissatisfaction.

Amazing! Was put on the earlier flight and I requested for an aisle seat and was given it. Thanks Qantas!

The crew were amazing - A great job. They made me feel special and valued.

Boarding was terrible - the ground staff member Fredeya at lax was more military than customer service, have never encountered a customer service representative as rude as her. Apart from that all other staff were wonderful and the flight was good.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

The flight was delayed almost 2 hours. Bad customer service etc. I will never fly Luthansa. Ever!!!

On time take off…US cabins look tired and need of refresh!

Fine. Though no food or entertainment so the survey needs to be updated with those options.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

Unable to initiate refund/reschedule the ticket #worst experience #lost 900$

Flight was delayed for almost 3 hours. Communication of gate change was poor. Email and screen said one gate and it was a different gate from that. Gate changed first to 64 B and then to 64 C. Originally it was 68B. 64C was not communicated properly!

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Plenty of room in the exit row. Sat on the plane an hour before taking off.☹️ Landed late and had to wait for gate availability.

Flight was on time early arrival better entertainment good staff.everything was excellent

Delayed leaving. On arrival we were taken to the airstrip and had to get off onto an over crowed bus, not all that passengers fit. Drove around the airport for 20 + minutes. Taken off the bus told to go upstairs 3 flights then all the passengers had to walk a mile or more , those of us old there was no one to direct us to were to go. I asked several people with no answers. Once I got to baggage claim my bags were not on the right bag claim. Once again asked for help and finally someone found my bags on a different carasel. Very frustrating.

Excellent host on board. Not so friendly check-in staff. Older plane with no food or entertainment due to short flight. Friendly captain and crew.

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.

They canceled the flight on us very close to the flight date .
