Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

Only water, tea or coffee served midflight, even to comfort seating. Man next to me needed two seats and took up a portion of my seat and Delta did nothing.

The flight was great as well as the airline staff

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

It was delayed but other than that it was great.

Got on the plane and sat there for an hour before departure.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

They double booked seats, the gate staff changed my ticket as I was boarding she went over to the computer and changed it without telling me. She messed up an entire three row section for me and others. Other travelers were outraged but the gate staff were so rude, so condescending saying it wasn't their problem to solve. I would rate this a zero if I could. Will not fly Delta again I'll stick with United and American.

It was nt delta. It was aeromexo. Service was awful. They served a very small drink and NO snack for a 3hr and 35min flight. Then for the first 30 min of the flight is was talk and talk over head interruption the movie/ show i picked to watch.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.

Same thing as flight from Pheonix to Newark. Uograded and Promised extra leg room and when I got to the seat it had none.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Everything except the food and entertainment. It was a great experience though

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

Flight was completely full January 9th? I problem i had the stewardess was bumping into me constantly walking by? very annoying.. on Austrian air I dint have this issue at all...

Amazing! Everyone was so nice and the food was so good!!

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

I was surprised how good an American airline can be - I was really impressed.

Excellent service throughout. Airport process is quick and easy. Very courteous staff. Great service in the plane! Just outstanding punctuality and service overall!!

I have paid for extra legroom on my flight. My seat was broken and did not recline. The crew could not fix it and refused to provide me with another seat

Over all experience was good. However the connection time was too short at CPG. We missed our connecting flight to AMS as the passport control line was too long and by the time we got our passport control done it was too late I wish there were some SAS staff to help us out at the passport control center Though they put us in a KLM flight from CPG to AMS, That flight was also delayed by over two hours

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

Flight was on time and the meal and service were good.

The accessible bathroom should be visible to people in Economy class.

Flight was delayed for 2 hours, then last minute the change to on time. The satélite location is far and a nightmare to get to.

This was a horrible experience. I’ve experienced several delays at this point and still not home. I was supposed to be home by 8:30 last night and here I sit at 7 am on a plane STILL unable to go home because of American Airlines.

Lexus in first class was absolutely amazing! Beat flight attendant i’ve ever seen.

Generally good. Flight left on time and the seats are comfortable. Plenty of space in front if you in you choose a comfort plus seat, completely worth spending the extra money given the amount of hours the flight lasts. The food tastes good but I would say it’s a the amount is too little. The crew was friendly and efficient. There was a some turbulence at different points into the flight. American Airlines has good deals to NZ if you book with plenty of time before you plan on going.

the plane was so hot!! the air-conditioning was barely blowing. The flight was delayed, and we had to sit on the hot plane before take off for an extended amount of time, waiting on international passengers. Would not have been so bad if it was not so hot. They said it would get better after take off, but it did not.

They are always late and seats was also not having working charger

We flew in first class. The crew did not offer drinks before the flight took off, but they treated us well during the flight. The food was excellent. There was actually too much food served, but it was nice to have all the options.

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.

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

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…
