I'll let Rudi answer your question Jamiel but when I needed a meal in first class (after refusing the chicken dish) UA gave me the "captain's steak" which could have been cooked a little more (like my steaks medium well) but good anyway. (not Smith & Wollensky's: Rudi's place; or Ruth's Chris, my place!)
So I guess they get the best food. Though I have seen F-A's eating the coach meal and once offering the mustard pretzel bags (there were NO takers!) CATMAN
