ok, now i am confused..and just purchased a ticket for my mom LAX-ORD-DEL-ORD-LAX..upgraded with miles on the outbound and chose 31J for the return as she is waitlisted and it hasn't cleared yet (weird because only SIX seats are missing on the seatmap on AA.com, but whatever...) Anyway, this flight is almost 16 hours...which would be the preferable seat on DEL-ORD, 777...is 31J ok? Only other bulkheads available right now are 31 c,d,e,f,g...is one of those preferable to 31J? please help!
