Hi,
Not sure but if your heli stuff is still valid?
Have you ever held a FW license? Than it could be a bit easier.
Ask CAA indeed.
What about the bizzJet scene? If you are flexible? It could bring more
relevant experience for an airline job eventually.
But it will be hard. All this MPL integraded schools fill up the seats of
the airlines.
Flying an helicopter is much more rewarding for your flyingskills.
That is almost none excisting in the Airline flying world.
And in the end it is a job. It needs to pay the bills.
Good luck.
