Aren't you only seat locked from bidding back to the same relative seat position? ie: back to the right seat of a narrow body. So if you leave the right seat of the 727 for the right seat of the 757, you would only be locked out of returning to the right or back seat of the 727 since anything else would be an upgrade.

 

c. Down/Lateral Bid Freeze
A pilot who is activated in a crew status that requires ITU training based on a down/lateral bid shall be frozen in that crew status for 24 months, commencing on his actual activation date. A pilot is not eligible for a permanent crew position award requiring ITU training with a projected training date during that freeze period except under the following conditions:
i. the pilot was excessed or down/lateral bid to relieve an excess; or
ii. the pilot down bid because of legal restrictions.

d. Administration of Down/Lateral Bid Restrictions and Freezes
Notwithstanding the provisions of Section 24.E.1.b. and E.1.c., (above):
i. A pilot subject to a down/lateral bid freeze or restriction is eligible for an award or assignment of his crew status at a new base.
ii. A pilot who down bid in his aircraft to a lower crew seat is eligible for an award of a crew position in a higher crew seat in the same aircraft type during the time of his freeze provided he advises the Crew Staffing Department of his intentions, in writing, at least 7 days prior to the close the bid.

 

Yeah I would hate to be locked into the 75 when the MD-10 FDA opens up. Seems to me 75 and the 77 are likely to be the only 2 acft with primary vacancies for a while. But always best to play it safe and keep your options open I guess.

 

Unless you get re-excessed!
