How can you have something lined up but don't know when it will be?
Obviously a different Company to the one you're in I guess but your post is somewhat vague.
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.
Shocking!
