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.
