TWA FFB/Aviators - Where is first class meal service?

Just flew flight 492 St.Louis to Miami on Thursday night and can you believe the first class food service was a box turkey sandwich.

I fly F Class Mia to St. Louis and they have meal service, how can they get away with it.

Perhaps because they appear to have a very narrow time window for full meal service. Checking their web site schedule shows that TW 492 is a snack flight, even though it departs at what I would consider dinner time(6:35pm), while TW 97 (MIA-->STL), departing at 5:40pm (the flight you reference for your return?) is shown as serving a meal. So, perhaps, 5:30-6:30pm is the window for full dinner service.
