In October my girlfriend and I are travelling MEL-SYD-SFO on QF.. We've booked a Monday flight as this originates from the Melbourne international terminal whereas Wednesday flights you have to fly domestic MEL-SYD, and the transfer system in SYD is quite simply a nightmare. Obviously seeing as we are travelling as a couple in economy it would be preferable to secure one of the two-seats in the rear of the economy section.
I've been told on this flight we must disembark the plane in SYD before re boarding approximately an hour later. Will this be on the same boarding pass? ie: If we secure good seats in Melbourne will they be ours all the way to SFO? Any help would be much appreciated.
