It was good overall but when I book my flight and seat through Kayak, AA will at times change those seats during check-in time which I don’t understand why. I always book aisle seats and had to sit at window for my flight to Austin this trip.

It was good overall but when I book my flight and seat through Kayak, AA will at times change those seats during check-in time which I don’t understand why. I always book aisle seats and had to sit at window for my flight to Austin this trip.

Nothing, I wont be flying American Airlines again and will not be recommending anyone to fly American Airlines. It was the worst experience flying I've ever had.

Short hop but nice crew, efficient processes and all very timely

The TSA check in took 1.5 hours to get through in Austin and I missed my flights back to DC

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

American almost always Delays flights from Austin to Dallas and back. I cannot believe they have such poor service on this route. I was about to switch to American from Delta, but they gave me enough reasons not to.

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

Domestic airlines have really fallen from what they used to be.

When I booked, I included my checked luggage and when the bill was sent there was no record of this. Its was costly since I am from Trinidad amd Tobago. Exchange rate over seven dollars to one US dollar.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The seats were roomier than other airplanes I’ve been on.

All the TV screens in my rows was non functional . The map shown for an international route was antiqued..

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

There was a fowl odour coming from the lavatory the entire flight

The flights are back on time and everything else runs perfectly.

Surly, unhelpful ground staff at JFK. There was a complete lack of empathy—a flawed check-in ordeal caused us to miss our flight. All airlines that I have ever flown would have worked to help me solve the ticket problem. Instead, frontline employees shrugged their shoulders and pointed fingers at us for having made an error. I will do anything to avoid EVER flying on Jet Blue again. It well deserves its low rank among airlines.
