meal service duration
With 4 crew in y/c on a 767 and a full ship a meal service will take approximately 2 hours.So if you are sitting in the front cabin of y/c you will have your tray for quite awhile.Qf removed a crew member some time ago.
Mel/NRT is usually operated by shorthaul who with no disrespect are still grappling with QF international service due to lack of training and experience.
