But, when the pilot demand goes up , then no-one will pay for rating.
IMHO this is WRONG - we are in a time of pilot shortage (relatively speaking) ... these, I have to say are actually the good times for those at the bottom and, more especially for those ready for an early command.
In other words, I think the days of inflexible and serious pilots shortages are gone forever. While that is just an opinion and only time can tell, I don't think it is an unconsidered opinion. In other words, the next generation of fALTP holders with 250 hours are already lining up with their hopes and debts ...... they will be even more desperate than the previous generation and will willingly work for next to nothing for their first job when the time comes. Ryanair has long known this and is sophisticated in its efforts to exploit such sentiments ... you, in turn, may come to see them in a different light.
