Hmm on balance I would suggest going for the Bus. Once you’ve got an A320 command then you can go anywhere you like. I’d suck up a few years in Eastern Europe to get further up the ladder while you still have no ties. The (im)perfect storm could be you settle down at your home base, the industry contracts and you’re now a family man with a less than stellar ticket to take to the next gig. It’s all a bit ‘what if what if’ but it’s worth some thought.
