Goodness, QF suggests on its website that the flight 'departed' at 2040 hours (2240 AEST) with arrival in MEL tomorrow five late at 0540 hours. A388 VH-OQA has its transponder on and presumably is QF36 (as it was QF35 earlier today.)
Given JessicaTam is on the spot, this must be a case of the QF software not updating the true flight status.
It'll be interesting to see if the flight ends up being cancelled. JessicaTam, if you have to spend the night in an hotel, would you be kind enough to inform us which one and details about meals and transfers, and how efficiently it was handled?
Passengers booked on the Monday 10 Queen's Birthday 0900 MEL - LAX QF93 should watch this space (although in theory QF94 arrival could form QF93 with QF35/36 tomorrow downgraded to an A333/A332 - lower seating capacity.
But I'm assuming the worst, so none may occur of that.
UPDATE: QF suggests departure of this 2015 hours SIN - MEL A388 QF36 will be at 2140 giving a MEL Monday 10 June arrival at about 0620, only 45 late.
