Just sayin'
This is exactly why we need to see frequent but smaller bids! For example, if you are a 727 SO and you bid A300FO, 757FO, 727FO and you are awarded A300FO or 757FO you are waiting 18 months for a training date but if you had bid 727FO first, you would have been in class the next month and be financially ahead for 17 months.
The company says, "bid what you want to fly". I say, If you are looking for money right now, bid the next highest paying seat that gets you into training immediately. Otherwise, wait 18 months for the highest paying seat you can hold. As far as passover pay scenarios, who knows? Of course, one may be able to swap with someone for an earlier training date but getting everyone in between to waive passover pay is not a guarantee!
