Boeing are simply providing the training. Scoot are not a TRTO right.
You get offered a job at Scoot and Boeing do the Type conversion.
If there wasn't a Training agreement you could just join and FoX Oscar when you want. What the Scoot Bond is like I have no idea, whether its enforceable if you run I have no idea. As I said before the terms in the Bond can often be viewed as a way of helping you decide if the Company is half reasonable
and not full of useless HR Muppet's sucking up to the Boss.
