In case anyone still wondering what is happening between Jetstar, Qantas and AA out of Perth later this year.......
I just checked my bookings on-line and called Qantas.
As from 1 July the AA flights change carrier to a QF flight.
No change to weekly schedule or departure times compared to AA.
My June bookig stays as is, with an AA flight.
Jetstar isn't going to fly from Perth to Bali yet, so we end up with a Qantas flight instead of AA. Won't make much of a difference to me, it was the departure dates and times that I wanted to make sure hadn't changed.
