The are flight schools over there, there are air taxi companies, right?
Actually, no. This is why the CTC-type route started before it became the monster it is.
There are flying schools around, but compared to the number of f/o's the LCC's needed a few years ago there is an insignificant number of instructors.
The overheads of running an AOC in Europe are so high that it is virtually impossible to survive running aircraft smaller than BizJets, and the operators are mostly looking for higher experience in f/o's than the airlines do.
The end result is that the route that I and so many others used to get into aviation just does not exist any more in Europe, there are not enough light GA jobs to supply the airlines with fodder for the RHS.
