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.

10.0 ExcellentAnonymous, May 2024MSP - YVR

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The plane was so outdated, that it made it uncomfortable.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

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

Great airplane The confort was within the high standards. My only little problem was That all the movies ( only 3) was on Spanish, even though I was selecting the audio on English it didn't happen. After that I highly recommend aeromexico

We were sitting on the plane for half an hour before we arrived at the gate after landing. We had to wait half an hour to collect our luggage.

Made payment for extra baggage online. When I got to check-in, they made me pay again. Lesson learned - Dont buy extra luggage allowence online, only pay at check-in.

Cons: "Plane delayed on tarmac on arrival. Immigration line was chaos with no staff helping to provide order. Missed my connection and changed to another flight the next morning - aeromexico would not pay for hotel or taxi. Supervisors were rude and dismissive, didn’t care about effect on my plans."
Cons: "Nice flt, competent and diligent cabin crew. But at ck in they assessed a $20.25 carryon bag fee even though my reservation via Kayak said one carryon was included. (It was within their weight and size limits) Even with empty seats they assigned me the non reclining row that abuts the restrooms (noise, smells, etc.)"

Well....let's start from the point that I had to stay in airport for 12 hours instead of 2 that was scheduled. Poor company and even worst customer service. Never again....

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.

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

very very tight seats unfriendly crew who do not seem to care about the comfort of their passengers and do not know how to smile poor ground staff support at LHR and PHX

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

AA1537 the AC was not working properly. It was very hot and uncomfortable.

So uncomfortable to sit in the tiny space on a long, international. Food was rough. Please, less white flour and processed food.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Overall good flight. The flight attendants were annoying and unfriendly. They would ask me to grab someone else’s trash can just waiting until the person woke up or after the flight is done. It’s not my job to pick up someone else’s trash. Especially when it’s not easily reachable.

The WiFi tv wasn’t working. The flight was over sold and moved several times. The gate assignment appeared on the screens right as we were supposed to board. Because of the flight being over sold we were almost stuck in Cancun for a couple of a days. The flight attendants were unfriendly and would wake you up to pick up other people’s trash.

The reason we chose Volaris to fly from LAX to Mazatlan, Mexico was because of the DATES and TIMES for the NON-STOP flights. When those flights got Totally Changed that was UNACCEPTABLE ! ! ! Also, when my husband Died unexpectedly, the Only statement that Customer Service kept repeating was "they would only offer Credit on a future flight". REALLY?! Volaris was only going to offer CREDIT on another flight to a DEAD PERSON ! ! !

Service of the person who gave us the boarding pass

Overall good but we had a minor scare when a wind shear caused the plane to re take off on the first landing attempt. The crew handled it well and we landed safely on the second attempt

It was unfortunate that I paid more than $120 one way to carry on my luggage to only have to have them checked baggage. We board the flight and there’s a lot of overhead space. They checked our bags in Group 2 but Group 3 was able to board with their luggage. I would not fly Volaris again. The flight attendance on the plane was very nice but the employees at the gate prior to boarding was very rude.

For the price, you pretty much can't beat this airlines. As far as comfort, you could do a lot better, but it'll cost you. Over all cheapest way to get from point A to point B.

To many extra fees, poor customer service and very uncomfortable flight. No leg room and seat wont recline.

I am disabled and was unable to get any assistance from Volaris. I had to wait in line at front desk for 45 minutes, I am by myself, and unable to stand. When I got to front desk check in, they had no assistance for me. I did however, have wheelchair assistance when I arrived in Mexico City. Thank God for that!

It was horrible, our flight back was overbooked and had to take a flight 12hours later in the day but to LAX. Volaris is horrible.
