I'm too lazy to pull up the contract, you can go to section 8 and look, but yes, you keep the bank money. However, make darn sure that it's in your expense report, for scheduled bank. And if it isn't, you can add it.

However, from the original question, it looks to me like they are separating out the mid trip deviation bank from the front and back. That is a serious giveback, if I'm reading it right. Because, say you have a mid trip deadhead, it stands on it's own. If you spend more to deviate, you can't use the other bank, and if you jumpseat mid trip, the bank can't be used for front and back. I don't know if that's how it will be interpreted, but doesn't that look like how it's written? Bad deal.
