I am currently booked in F Class ATL-LHR on Aug 31 (Fl #226) and LHR-ATL (Fl #227) and am trying to determine if there is any chance these flights might have the new BA First Class cabin. I can only find that this flight is operated by 777, but does not indicate if 777-300 (new) or 777-200 (old). Phoned BA this evening and agent could not tell me which routes the new aircraft were flying or if ATL was even scheduled. Seatguru indicates BA is currently flying new configuration on ORD-LHR-ORD routes. Any information anyone can provide is greatly appreciated. Thank you.
