The flight was delayed by two hours. I had paid for extended leg room. Due to the delay, the plane was different and I didn't end up having extended leg room. I finally was able to reach Volaris on Whats App and they gave me an airline credit. I wanted a refund to the credit card since I hardly ever fly Volaris. Other than that, it was a very comfortable flight.

In Mexico charges too much for my luggage and I ask for help and nothing one lady she just disappeared 😡😡😡😡😡never going to fly there

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.

Better communication about delayed flight. I am thankful for a small credit for late flight.

Liked on time, rear entry and exit from plane Dislike the use of duct tape to repair seat rests

Terrible. And they charged over $400 just for luggage. And threatened that I would loose my flight if I didn’t pay. So I didn’t have another choice but to pay.

They check you everything before entering to waiting room, if you have any liquid they take it away even if you buy it inside the airport, no recommend volaris, for mi know Alaska airline is better

They don’t give anything for free you have to pay for everything which it’s expected but at least give out water and a snack as a courtesy for flying with them.

I got to where I needed to go quickly. There were no amenities. And the seats were painful.

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.
