The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

The plane was delayed for over an hour because of a family who didn't speak English, and didn't understand what was asked of them. While I understand the delay, I thought it was unfair to keep us all waiting for over an hour to get to our destination and a better approach should've been exercised.

Finally get a snack n drinks! Just like the good ole days!

The website said ear phones were provided in first class. They were not. But a lot of programs had captions

I didn’t make it because Alaska schedule my flight too tight, I had to run to the other side of the airport, and no one helped me get off the plane early or held the plane for me… so I missed it and it was Alaskas bad, not mine

The flight took off two hours late and involved a gate and plane change. It might have better if they had announced a problem from the beginning, not when we were boarding. Annoying, but better to be safe.

My experience was great! The crew is great always happy and friendly :) thank you Alaska!!

We were delayed over an hour because of fog at the destination--not Alaska's fault, but it still made the experience a little frustrating on the day before Thanksgiving.

We were amazed by the amazing food, comfort and service received in our coach seats. Pleasantly surprised we received breakfast and great beverages for no charge. Bag check fee was on $35. The crew was so kind and helpful. Highly recommend!

SeaTac was a mess first class check-in not clearly identified Temporary signage needed since only one door into Alaska check-in area directed you to coach baggage check.

We could not find a parking spot in the garage so we left airport to find a parking lot. We were late and afraid we would miss our flight. We were greeted at the new Alaska check in and I was really upset. She got two people to put us in wheelchairs and we flew through the airport and security. Then all the way to the N gate and on to the plane. Somehow they hadn’t taken off. These two individuals deserve a medal for getting us to our flight and onto the plane. It all started with the wonderful greeter at check in. I wish we’d gotten her name and the two who got us there.

Free Wi-Fi is good. That’s all - food mediocre, unfriendly crew, poor communication after trying to file a claim for my lost bag, which Delta didn’t even know was lost until I told them.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Typical flying experience in the US. Nothing particularly good or bad.

Coach seating is debilitating, neither my husband or I can walk the following day

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

This is not a low cost airline. Stop acting like o e.

Aeromexico crew made me check my hand luggage in the door of the plane. As soon as I reach Mexico City, I notice that my luggage was opened and 8 games of Nintendo Switch were stolen (700 dllrs value aprox) (the console was there) but the games were stolen. I am very dissapointed of Aeromexico and all the crew. Instead of being a good trip, It was a sad trip

Ok. But we arrived to a remote terminal which meant that a bus had to take us to the terminal building

Old aircraft the audio of the entertainment dosent work Dirty seats

The plane was so outdated, that it made it uncomfortable. The temperature was hot during the whole flight

Happy attentive flight crew. All in all good flight the night flight works well. Getting into Mexico City early so you don't get caught up it all the immigration and custom ques, additionally, this helps when exiting the airport and crossing the city to your final destination. All works very well and would do it again

Some entertainment and food/snack service would have been nice

All the pessengers should be wait in a line útil the creo and piloto are arrived.

Planes seat could be bigger very uncomfortable for tall humans.

Atraso de dos horas y media con vuelos sobre vendidos

We arrived early and finally made it to our gate almost an hour after.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

horrible website for checking in- no option just to write the passport number; ludicrous

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Nothing, whole flight was a nightmare, was forced to check my carryon bag at the gate, staff was rude and unprofessional

David went above and beyond to make our flight the best that it could be

Was a pain having to leave the plane and reboard but glad the plane was fixed

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted
