At my original departure Istanbul I was told my seat and flight was cancelled from the 3rd party. I had no seat to get to my other flights .. they charged me $481 USD to board the flight that I already paid for

All went very well. We used the AIFI Airport, such a lovely facility. Definitely needs better transportation options to get there.

From the check-in, to the flight, and arriving, everything went very smoothly. Unfortunately, when I received my baggage it was severely damaged. I have a hard shelled suitcase and it was completely smashed it. I’m not sure how this could happened but I am extremely disappointed that my belongings were damaged beyond repair and continued use.

Lousy No wheelchair. As normal at Atlanta Cheap airline Cheap aero plane. - Neither entertainment nor food on a 5 hour saga

The plane was so outdated, that it made it uncomfortable.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

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.

1 hour waiting for suitcases to come out traveling in business class and food in business class is a sandwich? Avoid Aeromexico .

No space reserved for anyone who didn’t have underseat in front of them. Made it inconvenient to get the backs secured. No inflight entertainment in the 190. Bring your own! Food was excellent and we were surprised to get a full breakfast.

Just having a little bit more legroom would've been nice.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Had to find alternative flights because of AA lateness and bad planning

Delayed couple hours due to airplane maintenance issues, we boarded and then asked to unboard, but cmon!! Can they do the whole maintenance prior to boarding?

The professionals have excellent customer service, the seats don´t have enough space.

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

The flight was good. The only reason I did not say “excellent” was the delay

Flight delayed from rdu due to too much fuel. Had to stay overnight in dfw. Food vouchers inadequate to cover dinner and breakfast

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

Ground crew forced me to double pay for infant international charges, when I complained about this and told them, with proof, I already paid they threaten to not allow me on the plane because I was “being rude”. Horrible ground management, horrible airline.

My first time flying American Airlines, my first flight to CLT was wonderful and flight attendants was nice and had great customer service. My second flight from CLT to NY was very delayed due to whatever reason the crew was not greeting other than that I’m rate 8 .

Flight got delayed like 5.5 hours and the only compensation I got were 270 pesos which is nothing compared to the cost of a full meal at an airport or a hotel stay since the flight was during the night. No one seemed to know anything as of why the plane was delayed and I had a poor experience with the customer service line from the airline.

With a business flight, having a designated seat in the aircraft, I was denied boarding at the gate at last minute without any genuine explanation. The staff used profane language when asked for reasons. Viva overbooked and passenger had to pay for it. The food voucher that was provided did not even cover the the full meal and water for a single person. It should not be running in service.

Super BAD Everyone Behind the counters in Cancun Not Helpful At All And then on the second flight I Had to purchase Cancun - Guadalajara one of the flight Attendants Kick Out a Couple Out of the Plane and that Flight Attendant Had a Mask So People wouldn’t take pics of her and she was kind of Mean ! I Would NEVER Flight VIVA EVER THEY ARE NOT FRIENDLY AT ALL ! People think They Are Cheap but They Arent!!!

It was cancelled at the last moment and the customer services seemed unnoticed to this change and hanged me off the phone the first time I called.

Staff especially Alan Hernandez was a great help with arrangements for my partner and me sit together. This made the trip do much more enjoyable. Thanks so much.

One of the flight was delayed an hour. We then boarded a new flight. We were told to unboard after some other time. To wait for the next flight for another hour. I paid for a short flight that turned in to half a day of travel.

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

They cancel the fly and don’t give a money refund.

The air conditioner was poor and we were delayed 1 hour for no apparent reasons and no information provided

Overall a good red eye. Crew chatted very loudly the whole time making it difficult to sleep.

The fly was 2 hours delayed and the plane was old and dirty. A very umcorfotable flight, which I won't recomend to anyone

Confusion over extra fees. Held up on ramp during boarding. Thin seat cushion. Minimal leg room.

The check-in is either at a kiosk that didn’t allow me to check-in because my middle name was not on the reservation or at an agent that cost $15.

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;(

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!

Our flight got overbooked and we missed one day of our trip.

Be prepared to pay extra for everything! I'm not sure I really saved any money?

Check in at LAX was terrible. Unbelievable lines. Chaos. The landing in Morelia was scary, with the plane fishtailing. If other airlines flew directly between California and Morelia, I would never fly Volaris again.
