Thus given;
EK need 800 pilots next FY
Do you have a source for this assertion?
Pilot supply is global.
Not really. A 737 Captain in Australia cannot work in Europe without gaining an EASA licence, which takes a great deal of time and effort. This is a major barrier to the free movement of labour. I think designed to protect local jobs. I mean if foreign pilots can fly in to Europe safely on their foreign carrier why then can that same pilot not fly in Europe in a local aircraft? The answer is simple but the reason is nonsense.
If you want to talk about "global" I think of a web designer who can work from anywhere in the world with a good internet connection.
