Everything was done like clockwork and I find no fault with the airline.

Like all planes recently, entertainment is achieved by giving the patron free WiFi and letting them stream shows via the screen on a phone or tablet.

I thought American Airlines did well considering the adverse weather situation over July 21 and 22. I especially appreciated the consideration given to me when I got stuck in Miami on my way to Boston from Charleston, West Virginia. Thank you for providing a voucher for an overnight stay. Though it was only a few hours of sleep, it was very helpful. I was able to reschedule my medical appointment and got back to the Boston area on the 1st flight out of Miami as a standby passenger. It was very helpful that I was given number one priority on the standby list.

- flight was delayed several hours due to weather (understandable) - flight delayed further and we were told by attendants "we are not sure where the pilots are but they are on their way" as we have to find different pilots for the flight - announcements over the PA were somewhat unprofessional by the attendants, seems they need more training and were not reading off the script. They showed their young age and immaturity in their communications with the passengers. They were not clear and lacked professional communication language. - going from a hub to hub we were also parked at the tarmac at ohare for an additional hour and kept being told "few more minutes". Please just let the passengers know the real wait time instead of hiding the truth. We understand there is traffic and weather delays, but we just want transparency. There are several logistics of our lives that revolve around what the attendants and pilots are sharing with us but they are not being transparant.

As I said I never took the flight back from due to earlier delayed that prevented from taking the second trip back and nobody helped me to rebook from kayak

Would have been good to have the live TV outside of the continental United States as AA was promoting they are sponsors of the Fifa World Cup only for the live coverage to end.

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The plane was broken so we had to change planes.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

It was an early flight and most people napped/slept and the crew let us which was nice.

First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.

It didn’t happen. I booked it and then was told it wasn’t available and then forced to pay far higher prices for a worse option

The worst. They don’t follow procedure for boarding per group. Flight got delayed for no understandably reasons, they changed our destination from PR to Miami, left us inside a plane for more than 8 hours, then cancelled flight in Miami leaving us stranded. Poorly managed re-accommodation for a new flight and overnight stay so I have to spend in a new ticket and my own hotel room to been able to get to my office next day. Lost 2 days of work and as a doctor, patients loosing their appointments. to other flights and besides

Although an hour and a half early was told by staff at check in they had overbooked and could not check us in for the flight.

I liked the price of the flight and the chance to buy a seat with no person seated in the middle seat.. Also the flight was right on time.

The flight left over two hours late. They charged me $180 to bring a carry on. There was an error with the spelling of my name and Frontair agent lied that I would need to pay $200 for her to fix the spelling, and pressured me that if I don't do it quick I would lose the flight. I called back and another agent said it costs $75 to fix. All in all, this company is a complete scam.

I took my first and last flight with FRONTIER. The seats are not able to be reclined so it’s not a very comfortable experience when you take a flight of 3 hours or longer. You must pay for your luggage either carry on or check in, so taking all this in consideration at the end what you think you’re saving your paying in services that should be included. Not a beverage in sight. . You’re seriously better off getting on a proper airline such as Delta, AA, United, etc.

Frontier notifying me earlier of flight delay of over 2 hours.
