No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

No food/snack served during the flight. Crew wasn’t interested at all. Flew American First but flying low cost with Ryanair is even better

Good crew and a great experience. Only good things to say.

The flight was good. The only reason I did not say “excellent” was the delay

Great thanks - a whole row to myself. Good food but film selection not great.

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

Flight delayed from rdu due to too much fuel. Had to stay overnight in dfw. Food vouchers inadequate to cover dinner and breakfast

It is okay. Flight was on time to start and early to land

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.

Boarding was a shambles, pushed us all onto the airbridge and then made us wait for ages
