My experience: hot bites gone from most if not all TATL. Haven't been on West Coast - FRA lately to find out if the ultra-long TATL still have it but I've personally not seen them on flights even as long as SFO-LHR. Absolutely 0 hot bites out of ORD TATL. Menus and other marketing collateral no longer reflect 'hot bites' but rather refer to 'snacks.' No hot bites on shorter TPAC either.
