Simply being assigned a training date is not sufficient to hold onto a bid.....at least, according to the T&PA.

c. Pilots who, at the time of implementation of an integrated seniority list, are
in the process of completing or who have completed qualification training
for a new position (e.g., B-777 Captain or A-319 First Officer) may be
assigned to the position for which they are being or have been trained,
regardless of their relative standing on the Integrated Seniority List.

Yet, in the Bid posting, it says:

As stated above, this System Bid differs from previous System Bids and is intended to
transition from separate sCAL and sUAL filling of staffing requirements. At the time of the
Seniority List Integration, pilots who have not been awarded a Training Assignment Bid
award resulting from this or previous System Bids will be considered to be in their
currently staffed position for purposes of bidding on future Vacancy and/or
Displacement bids. As an example, you are a IAH-777-FO today and are awarded on this
System Bid the position of IAH-737-CA. By mid July, TAB’s should have been awarded
through October. Should SLI occur in mid July and you have not been awarded a TAB award,
then your position for subsequent Vacancy and/or Displacement Awards would be IAH-777-
FO not IAH-737-CA. Further there would be no pay protection entitlements to positions
unfilled from previous System Bid awards. The expectation is that all United pilots would
compete for those vacancies for which training and advancement has not been scheduled,
based upon their new seniority.
