I agree with Dr.
It is a small price to pay for such sought after training and seeing that you are paying the money the company expects no loyalty in return. Alternatively if you were bonded like some other company's do you would have a return of service expectation placed upon you in the order of at least 2 years.
This is working fantastically for the people who are joining sunnies and eastern at the moment as they are not expected to stay. So therefor they are joining, enjoying the training, and moving on to jet jobs within 12 months!
Don't be turned off paying $10000 as there are a lot of hidden benifits!
