The flight was on time and arrived early. The crew were friendly and helpful.

While I didn’t watch much tv I would have liked a few more options of TV series from Apple TV or hbo max ..

Overall experience was great. Flights were almost on time in departing and we arrived at our destination as scheduled. No issues with amenities or flight crew. Everything went well as as expected. Will fly again with American Airlines in the future!

The flight was very smooth and the meal in business class was great.

I requested a low sodium meal. Reason being, I take medicine for high blood pressure and I wear compression socks on long flights to help with leg swelling. Having less sodium in meals really helps me feel better on long flights. I received my initial low sodium meal after takeoff. Just before landing, the crew came through with the meal cart and offered me what was being served. I said no thank you and then noticed my low sodium meal in the meal cart, with my name and seat assignment on it. I motioned to the crew member, but he grabbed the meal cart and proceeded to move to the rear of the aircraft. He didn’t see me or other passengers who had attempted to get this attention. He was more concerned about completing meal service since we were due to land in under 45 minutes. I pressed the call light five times from my seat to receive help, but no crew member responded to me. So, I didn’t receive a second meal, one that I requested (the low sodium option). This led me to have a migraine from only eating one meal on an 11-hour flight. This is why I’m not a fan of flying US-based airlines overseas. The crew members continue to show the absolute worst customer service experience. I would not recommend flying American for overseas flights.

Not great. Booked Extra seats and got nothing extra at all. It’s basically a big budget airline.

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

The flight was smooth, the pilot kept us informed about delays and we arrived more of less on time

The flight was flawless and we even arrived between 20 and 25 minutes early!

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

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.

No entertainment, charging, nor wifi on board but I napped for basically the entire time so it was alright. Was allowed to switch seats because the flight was not full but everyone was assigned to the back. Comfortable seats and we got moved to the emergency exit so the extra room was nice.

Painless trip. Only downside: No entertainment system (which we know with Viva & Volaris) and very small seat space. I'm petite and felt squizzed. I'm not sure how most overweight passengers do.

I was charge $90 for my bag more then the fight crazy!! And the plain hit a couple of birds on the take off bird strikes we returned back and had to change planes bad customer service everyone has an attitude problem!!! Bad experience!!!

The bad thing is they didnt send me the deatils about how much alowed bagage ehight 1 carryon or cheacking bag Also they just send in spanishlanfuage i couldnt understand emails

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

They closed the gate over 25 minutes before departure and I didn’t get to board.

No empathy for my situation, arriving at the check-in counter 5 minutes after the deadline to deposit baggage due to a very delayed incoming intercontinental flight. The attendant simply stared past my shoulder and picked up the microphone to announce a "reminder that all passengers must arrive at least one hour before the flight" before speaking to the passenger behind me. I understand that there are rules above deadlines but at least show some damn empathy. It was Christmas morning and I'd been travelling for 20 hours for goodness sake!

They no longer offer anything free to eat or drink, everything is sold, not even a bottle of water is offered for free.

It’s a 2 1/2 hour flight so good and comfort was not my real concern. Safety, easy, fast was what I was looking for. The crews were great, plane was clean, boarding from CBX was fantastic! Definitely traveling this way again.

The money you save flying volaris is not worth it

Is was a good short flight with some turbulence! I would fly Volaris again.

We had boarding passes for the next flight but we could not catch the flight in the small airport just because volaris closed the boarding at the counters an hour before for which we had to sepnd almost 3+ hours to catch next flight. There are hardly anyone who can speak english, but thank God, we have found an young man who could not only speak English but helped us book for the next flight. The air crafts are noisy and scary sometimes to hear that squeeking noises during the take off and during the flight. They do not even offer a cup of coffee for free in flight. The prices are super high and the services are zero. That’s pretty much for this airlines in summary.

Unfortunately it was not a good flight got canceled had to be at the airport all night long to get a different flight to another airport my first flight with Volaris was very bad. Poor services

The boarding , and it would be nice if they would let us know head of time about flight changes

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.

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.
