Very good flight. Crew was great. No issues and we even arrived early.

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

The gentleman at the gate I think his name is RIE was exceptional

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

I rated the experience "mediocre" because of the 2 hour delay in take off. This is the 4th flight from DFW on AA where there was a delay and in one of the instances (after 13 delays), the flight was cancelled. I understand weather but for the March 18th flight, there was no weather issue in Dallas or Detroit. I called Concierge Key and they were wonderful, booking me on a later flight in case my flight was cancelled. I have flown with American for many years and never has there been this consistent pattern of delays. Very disappointing.

My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

The offered WiFi on AA isn't worth wasting time or effort on. If you manage to connect it's incredibly slow.

The service was good during the flight, but booking process was arduous due to mysterious partial cancellation (on the return leg), which took me 1 whole day to connect to the RJ’s NYC ticketing department to straighten it out. The reservation line of RJ customer service said they did not have the authority to un-cancel it, nor refund the ticket. To undo, I would have to email the NYC office and wait 5-6 days for reply, while my departure is 5 days away. Then the NYC phone number given (and I also found on their website) had no one answering, until I got someone in accounting or HR department to transfer me to ticketing dept. Then the seat upgrade at the gate only takes cash, no CC. From speaking with other tour mates, other airlines were given them the similar headache too - cancelling part of the trip without rescheduling options.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.

sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.

Both legs of the flight were changed. The day of the flight and length of the trip.

You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines

Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.

They switched my flight to Spirit, Never using Kayak again,

There were a lot of issues at the gate in Atlanta — which caused delays in boarding and getting to our destination. The aircraft and crew were excellent.

It was fine. The flight was delayed for 3 hours. I had things scheduled in Detroit, and I let a lot of people down by not being there on time.

Flight was canceled as soon as I got to the airport
