I turned down an interview with Cathay 8 1/2 yrs ago. To stay in OZ I have not regretted my descision for one second. But I have kids and a family. 10 acres 2 horses a happy wife and kids is pretty high on my list of priorities.
I love flying but I do this to be paid a wage to provide the lifestyle with which I can educate and bring up my kids in a safe environment Ask yourself. Where do you want to be in 10 years. The aircraft you will fly be it a dash 8, 737,747
will just be another bit of tin after a couple of years.
Good luck with your descision and hopefully it will be the right one
cheers
