Work out what your payout would/will be. Do you have any debt/mortgage etc. Are you ok with moving state/country? What licenses do you have?
The job market for LAMEs/AMEs is very very tough. If you only have a 767/747/744 license you have little to no chance of getting a LAME job anywhere in the world. I know people with full B1 licenses with B767, B744 & B737-NG who struggle to get a jobs. I know some gents who moved off the floor and went to Virgin due to lack of LAME jobs.
I would only "jump ship" if you are an AME and you get a job at jetstar or virgin. Other than that depending how old you are I would maybe think of changing careers. The biggest thing everyone at QF are going to have to realise is you are not going to find a job that pays what you're on unless you go to the mines etc and thats not as easy as Gillard makes out. good luck.
