Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

I would like a refund for the extra cost the seat I paid for. An oversized person sat next to me and I couldn’t fit on my seat and had to move to another seat.

Boarding gate at LAX was too crowded—two gates next to one another

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

This flight was delayed but it worked in my favor because my Atlanta to Dallas flight was delayed.

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.
