We were told the flight was delayed 5 times, then it was moved to the next day.

We were told the flight was delayed 5 times, then it was moved to the next day.

The experience with American Airlines was good, although the Philippines Airlines flight was much better (better seats, better food, better entertainment options, overall better). Again, the MIA to LAX flight was fine, but nothing in comparison to the comfort and accommodations of the Philippines Airlines flight from LAX to MNL.

Loved the crew . Absolutely no complaints. Except for luggage lost

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

We are too tired and frustrated to comment politely at this point

The business class seats are dated and uncomfortable. The space is bare minimum and there is absolutely no privacy. For $4K, this is not what I expect.

We spent too much time on board waiting for takeoff.

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

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

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.
