Am seeing the same type of seat map (BusinessFirst section larger/wider than other sections, seats shown as boxes not directional seats) on UA 929 (LHR-ORD) flown by a 777 for a travel date two weeks from now. Oddly enough, not seeing it for a return the next day on a 777 (IAD-LHR). I assume it's just a weird glitch, but a pain when it comes to forward versus backward facing seats...
