I just booked LHR-NRT using my 2-4-1 voucher for October 2020. I booked in a rush at midnight to snag the club world seats and belatedly saw that the NRT route will be a 777 in October- a shame as I was looking forward to the 787 experience- especially as the club world cabin on the 777 looks rather large and dormitory-like. Last time I flew club world on a 777 was to Bangkok and the engine noise at the back of the cabin was very loud.
