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

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The plane was so outdated, that it made it uncomfortable.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

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.

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Booked a united Air flight with option to pick seat , then found out was on an Air Canada flight with assigned seat , then they wanted a several dollar charge for some 25 cent value entertainment listening ear device

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.

Seats are outdated. Entertainment relies on personal device. Boarding was delayed due to inaccurate passenger tracking, resulted in late arrival at Reno.

Excellent staff helping my 96 year old senior promptly with her oxygen needs

The crew and flight was amazing. I haven't flown United in years but plan to switch to you being my main airline

It was as expected for such a short flight. No complaints

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Crazy seating issues. We got seated far apart. Offered middle seats at a premium rate. Why is a middle seat now the expensive seat? Baffling.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

Flights were on time. That's the main consideration since I had to change planes. The entertainment was whatever you bring with you and the food (in Economy) is non-existant. Neither of those was a surprise.

I paid for Viva play and most of the time didn’t work and also I order some drinks and the price was to expensive.

The terminal and gate was never the right one announced in the Viva App, neither in screens, moved from one terminal to another

The smart/express line to check in was a mess, employees not doing the process smooth and quick, using their mobile phones, talking to their coworkers

My flight was changed 4 tienes , delaying my arrival lore than 5 hours

Everything was okay, but boarding begins late and when I was returning there was a gate change. The app never showed the change.

Flights were delayed both ways, with no communication provided by the boarding desk. Delay time kept changing and the boarding process is a pain, as it is so disorganized. Would not recommend.

NOTHING.. THEY CANCEL MY FLIGHT WITHOUT NOTICE AND ENDED UP BUYING A NEW ONE..

They changed the booking I had twice. I got an email last night at 10pm (which I missed of course). Went to the airport this morning and found out it got cancelled due to plane maintenance issues. They offered a flight for tomorrow morning and I just got an email with cancellation notice. Again!! I would not recommend booking with this airline.

THE AIRLINE FUCKEN SUCKS... NO DAMN PROFESIONALS.. NO CURTESY THEY CANCEL THE DAMN FLIGHT AS ITS ABOUT TO TAKE OFF

They need to have enough immigration forms for every one. They should offer free water to everyone, unless some one needs bottled water

The worst. Kayak sent notification at 2am and 10am regarding the delay. Then sends a notification an hour before original depart time that it will depart on time. I had to wait 8 hours at the airport. My family had to pay for lodging in Guadalajara where I was landing for pick up.

They were only able to give me a seat and not my travel companion, she had to fly on a different airline. unacceptable

Stood inside the plane for more than an hour before take off

The app doesn’t work. I am having a lot of trouble checking in for flight tomorrow. Very disconcerting. Then they es t to charge extra for checking in at the airport;(

When booking I was not made aware that my flight would be standby. I was told when checking my bags that I purchased standby tickets. Luckily there was enough room but an unpleasant experience to say the least.

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
