I've gotten a lot of odd stories about this.

Before I flew last week, I heard that they were not serving food on NWA domestic flights at all, but at MSP they told me they were serving food in all classes that were flying from a NW hub westward only. Thus, we got food from MSP-LAX.

When I flew back, they fed us again. This time they told us that they are serving food on all domestic flights over three hours in length.

I'm not complaining, but does anyone know what the straight story is?
