By the looks of it, if you have a look at it, on the 11 Jan, ADL - DEL leaves at 8.15am, a bit early for a MEL - ADL flight, but if you put in a search on the QF website, MEL - DEL, it routes you via SYD.
And that is the direct flight option.
Not sure where that 330 is coming from on that 11 Jan Tuesday morning, maybe its a flight from the east coast that will fly to ADL the night before with freight only, who knows.
I used the former immi on flights to NZ, but have not tried the new downstairs immi processing at ADL airport, so maybe, with it being wider, international flights from ADL would be better now, outgoing immi wise.
By the looks of it, its wider too, with more immi counters, and also more international screening walkthrough scanners, and more wider zigzag bunting.
They still then marshall people upstairs to the closed off domestic gates though.
Not sure either if that international lounge is ready for pay per use entry, the one that SQ gave up on, that zone probably has gotten torn up for the new immi processing zone.
