If prices go up over night for something obviously it's in demand, when the price drops it's not so popular.
If I was to do line training I wouldn't be returning to Europe for a job, I would be going to Asia and the Middle East. Europe is in a spiral for the past few years and the schools are still pumping out the students like there's no tomorrow.
I know a guy in Congo too, no ILS, no Nav Aid, no Radar, no separation from ATC. It's pretty much like bush flying except in an A320. I'm not sure Airlines would consider that sort of flying tbh but who knows and I certainly wouldn't pay 50k to do that sort of flying in Congo.
Asia is crying out for expats especially Europeans as the license is of a higher standard, apparently....
