I am not suggesting that all of the food on Delta is bad, just the food loaded in Atlanta.
I live in Atlanta and on all of my outbound flights the food is awful and the food on the way home is always fine.
My recent experiences include, atlanta to: LAX, SFO,SNA, STT, NRT, ICN
The domestic outbound including STT is worse than the international but the international is far from good.
It is amazing to me that the food loaded in STT is so good.
I really think Delta should do something about the food loaded in Atlanta.
