Excellent experience. Welcoming, comfortable and stress free

Movie selection was meh. Food was great. Crew as always great. I paid for premium because that’s the only way not to feel like a sardine. That’s how economy should be imo. Sadly passengers have to pay an extra $1000 to get what they should at base price but that’s all airlines. The airline industry in general treats passengers as cargo.

4.0 Mediocre
Gate agent rushed to fill hot jetway with crowd so it took over 12 minutes to go from gate to plane. Just like a discount airline Pooly prepared cabin and third time that claim of rough air prevented any cabin service. Friends on a Southwest flight at similar time had service.

My only complaint on any flight is meals but your gnocchi was good. The worst is breakfast. I can’t understand why you don’t just serve something simple like yogurt, fruit and a muffin or cinnamon roll.

Cramped seating for me. Luckily it wasn’t a long flight

The crew was very nice and very attentive. However, I was surprised to find that they did not carry small throw-up bags. I got sick from the turbulence and they had to bring me a trash bag.😳 You can imagine how embarrassing is to lift a large trash bag with vomit over somebody else's head. Just bring this small discreet little bags back to the regular supply for the seats. Otherwise, I love Delta airlines.
