BA33 on 13 March. BA seat map has changed, all the bulkheads have disappeared and aircraft type now listed as 78C. Same number of CW seats and layout as 787-9 (except for bulkheads disappearing, although the bassinets still show in row 10, implying bulkheads will be there).
Expert flyer shows it as as 78C, being nosey and trying to check First and shows an error. The KUL flight normally operates a First.
