My understanding of the situation from talking to SEQ crew is that if you live closer to OOL you are rostered day trips out of OOL and 3 and 4 day trips out of BNE.
If you live in BNE you are rostered most flying out of BNE. You can be called to operate out of either port.
Everyone is saying Impulse will stop flying to OOL from August. The a/c could be better used elsewhere. (With bigger planes going to OOL - all Y/C 767).
There are FAs in many airlines that commute across the country or drive for two hours to start work. Life is about choices, QFskywalker. You decide - no one will force you to do anything.
