Airline reviews

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 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.

Inept company. Won't fly again with them if I can help it. Plane was the wrong size and they couldn't board 20 people.

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.

necesitan mejorar el entretenimiento, en vuelos de mas de 3 horas

When you make the 3 Lines to board de airplane , I believe that you should make only one line first and then call the next and then last ,,, because the number 3 wait to long just standing there ,, my opinion !!!
