^^ Correct, and its because of this "middle man" status that they've screwed a whole bunch of pilots. Because you have no say regarding your training with Oxford, you have to negotiate everything with GAA, so lets say something happens during training in Oxford where you are located you need to call up someone in Bahrain and hope that they understand the situation, and most likely they won't.
Don't waste your money with GAA, you can do everything GAA promises you for a fraction of the cost by yourself. Its not as though every Second Officer in every airline in the ME has come through GAA. Most have paid for their own training and have got in on their own merit. Don't let the fancy name and their status fool you, at the end of the day if circumstances change so will your chances of getting your guaranteed job.
