Ben Sandilands has been critical of QF for the number of toilets on the B787-9 saying it will be a nightmare should 1 or more toilets go u/s. Virgin Atlantic has begun LHR-HKG-LHR with the B787-9 and with 198 economy seats there are only 4 toilets in the Y cabin. Totally inadequate for the Chinese bladder. A sign of the times I guess.
