All I can say about all of this is what a wise man once said to me.

Bid what you want.
Want what you bid.
Careful what you bid for because you just might get it!

A year after I was hired (a long time ago) the 767 was 1500 seniority numbers senior to me on a bid that closed in Mar. I decided I would hang out on the panel on the 727 until I could hold the 767, so I put in the bid and figured I would get it sometime way down the road. On the vacancy bid that closed in April with no 767 FO positions advertised in my base, I got the 767!

We are blessed to live in interesting times, so just like those folks that got the WB bids a few years ago, if you put the bid in you better really want the bid.
