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.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Flight was on time, no drinks served on the two short flights. Comfortable seats.
