You normally could only "lose" the bid in basically two ways:
First, if you didn't really want the bid you would advise the company of that and they would be required to continue to advertise your bid until you went to training. Keep in mind that in this scenario any bids that the company wants to put out, come before the requirement to put out your bid. So, if there are still unfilled Captain bids on a vacancy for positions that the company wanted to fill, then you still have your bid. However, if the music stopped and the company was happy with the number of Captains they have but you didn't want the bid, they would still need to advertise your slot until you went to training.
Second, (even if you wanted the bid) if the music not just stopped but started going backwards and the company decided they had too many Captains they could issue a displacment. Displacements are done in inverse seniority, so they would issue displacements to the juniormost number of Captains the company wanted to reduce from your base. Senior folks could volunteer to be displaced, but absent that, the junior folks would be displaced and allowed to go to whatever position their seniority could hold system wide.

Given the number of retirements coming up it would have to be a major event to get us into displacements/furloughs, so the second option seems pretty unlikely in the near term.
