a. There is no guarantee of a job anywhere, irregardless of the choice of FTO.
b. As all of the applicants are Bahraini nationals, they wont be able to secure employment anywhere else in the world apart from Bahrain.
This is very well known I think.. and my words about the job guarantee were just to roughly point out the value of having EASA licence issued from the UK CAA after an integrated training course with OAA!!
While for working in the EU, it's already impossible for those cadets to work there because of other reasons that are very VERY well known too!
Whilst the bigger airlines in the region such as Emirates, Etihald, Qatar Airways do accept pilots fresh out of flight school, they have policies in place which limit applications to their own nationals (just like the policy Gulf Air has).
Many things could develop sooner than you think! you don't know how could something like GAA change the rules!!
