Anyway, it's a damn shame you don't feel like coming just because of the bond issue. Why not ask them to make an exception for you as you don't feel it's right that an Airline should spend tens of thousands of dollars interviewing you, training you in classrooms, simulators and widebody aircraft, providing free furnished living accommodation, uniform and interest free car loan and then expect you to stay for at least 3 years.
If the job was worth keeping then it would not need a bond!
A bond is only away to under compensate an employee in order to keep him from costing the company money.
I think any place with a bond has issues.
