I would think very very carefully about taking a huge loan & then going training since there is no job guarantee, no matter what the guys at GAA say. Remember at the end of the day they are there to make money so the more of you they convince to take a nice big loan the better there bottom line is. They claim that they will help you find a job but with who-GF is very quickly going down the toilet & no longer has any ties with Mumtalakat, Bahrain Air has plenty of its own problems & I would be surprised to see if any of the 2 will be expanding within the next 5-10 years.
Sorry to ruin many of your guys dreams but just ask around coz there are almost +80 cadets sitting around Bahrain after their graduation waiting for a job & many cannot even find a non-aviation related job.
Bottom line-unless you have money to throw away I suggest you stick with whatever job you have.
