I just looked at the QF schedule BNE-PER for Saturdays in Feb
And the connections all require leaving BNE by 18:00
Looks like an overnight in BNE will be needed Sat (not Friday)
Will have to work on some other reasons to spend time over east
Edit:
What else is going on in BNE? the 0820 and 1000 BNE-PER flights on Sunday 20th are FULL. (ie Biz only)
