So this means that ex-SIN, QF opens their flight for check in as early as 1 day before STD, while in SYD, QF only opens their flight 3 hours before STD?
One of the many reason why I would like to check in early is to get myself on one of those 2 seaters at the back of the 744 (I like my window seat, but dislike having to climb over more than 2 persons).
Without the option of online check in, I guess the most primitive solution is to get to SYD airport 3 hrs early.
