Well, if you fly in the morning, you will get the traditional breakfast with a choice of hot entrees or good old cereal. Yogurt is also available...
During lunch and dinner times, you will get a choice of hot meals with a nice appetizer, a salad, a roll, and the infamous chocolate cake.
The only flights without meals are the redeye flights, which I don't think NWA still has redeye form LAX to MEM.
Enjoy the flights!
