I doubt that will be the case. People aren't going to tolerate that sort of wait. It really shouldn't be more than 2 hours.
How do you figure that????
the QF1 & 9 will arrive Dubai between midnight and 2am to then depart for Heathrow about 3am for the 6am landing slot. From what I'm told most of the Emirates flights depart Dubai between 8-10am for Europe. So based on that I'd say thats any where between a 6-8 hour transit.
How do you come up with only 2 hours????
