If you do want to go home in probation, you MUST ask your manager. I know of a girl who tried to 'sneak' and was found out- she got sacked.
It IS possible to do, but you have to clear it first. Some people think they can do whatever they like, but really it is not fair for some to break the rules to go home early when many many others had to wait the 6 months.
Yes it is tough. It's nice to go home but do be prepared in case they say no. A girl I flew with recently only went home after over 8 months in the company- she had asked to go after 5 & 1/2 (for family event) but was refused.
I think this can depend on which manager you get and also how busy is the flying (no hope over christmas/busy times)
As Mari says its possible to use combination of tickts but you need to have a second plan, just in case!!
you could get to sydney but lots of flights are full full full.....
A friend from Melbourne takes a flight to Perth then buys a ticket on domestic airline (e.g cheap from Jet Star or Tiger Air) to Melbourne...
