Going from Q400 to an Airbus is not a big deal.
You know it, and I know it, and many other prop drivers, but seems like 99% of the recruitment departements world wide disagree about that.
I know people who moved onto a 777 or 748, with only Q400 hours in their log (a few lucky ones). And many performed better than the stick flyers.
Too many jobs overseas require those "on type" or "jet" hours.
