No Joke possibly you are on the wrong thread? We are not debating paying for your own training, we are talking about Training Bonds.
Just so long as you complete the return of service the company require after being cleared to the line there is nothing to pay.
If a company require you to pay for your own training over a period of time by deduction of salary then that is not what is widely known as a Training Bond, the very word 'bond' implies a promised amount if there is a default.
Getting tired of saying it

but those of you that don't like the idea of a training bond and advocate doing a 'runner' are the very reason we now have training bonds.
For anyone thinking of jumping ship here is a scenario I have seen played out. Half way through the bonded period new pilot jumps ship, not a word to anyone. Ops notify HR who pass it on to the legal department, either in-house or out, (in-house in the case I describe). Jumper is brought to court, complains bitterly about the inhumanity of bonding, how over priced it was, how 'unfair', etc. etc. etc. Jumper is asked, "Is this your signature on this agreement?", Jumper, "er....yes". Short lecture on Jumpers lack of knowledge of contract law and case found in favour of the company with all costs. Jumper now not only has to pay his bond off but also an equal or greater amount in costs, is that anyones idea of a victory for the Jumper? Didn't think so, doing a runner is professional and financial suicide.
