I am scheduled on NW 346 sfo-dtw march 31 at 10:40 pm. I'm a Delta plat and have been upgraded. It says there is no meal service in first for the 4 hours and 20 mins we'll be in the air.

I'm also on NW 355 April 2 msp-sfo at 9:15 pm, shows no meal service for a 4 hour flight.

Now delta doesn't have a full "meal" on a redeye but they do serve a cold sandwich and salad. my question is, is there any real food served at all? thanks in advance.
