Yes, in business, supply and demand pretty much sums it up. However, there still remains the problem of the uneven playing field for pilots at present.
BALPA is suppossed to be challenging the rules regarding pilots paying for their type ratings and P2F. This is a major hurdle for a lot of experienced pilots because airlines like RYR have destroyed it for everyone.
If the 1500 hour rule was brought in like in the US with regards to joining an airline, this would suddenly change the supply and demand rates of pilots in Europe with experience in the pilots favour I believe.
I completely agree there is an over supply of pilots at present but the problem is that the industry is so badly run and until that changes, it will remain dire for crew.
