I flew this flight last summer and no passengers are allowed on or off the plane. Other then the porters who come on to freshen things up, I believe they switched out crews also as we had new flight attendants serving us.

Also, I believe they fuel the plane as well... which I do not understand why unless we are loaded down with tons of extra cargo in the hold and the winds are not in our favor. ET flies 777-200LR's which have more then enough range to make that run.
