10.0 Wonderful
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

It was nice. No issues

8.0 Very good
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.

Lounge in Lagos is terrible, food on board from Lagos to Atlanta was horrible. Only bright spot the cabin crew were awesome.
A
6.0 Okay
The airport was reasonably clean. The boarding process reasonably efficient. The cabin crew was efficient, polite but not that friendly. The food quality was unremarkable and the choices were awful . There was either a so so chicken dish or a “ vegetarian “ option which was really cheap carbohydrates drowned in cheese. Signing onto i flight wifi was not straightforward. Overall it was a very average experience
