For those who've yet to memorize C2016, 13.K.11:

The Company may in its discretion on a bid or pay period basis waive the criteria set forth in paragraph 7 above and specify that all open time will be paid above guarantee. The waiver may be fleet/seat/domicile specific and further may be by category of line (e.g. RMUL, EDW, EDW turn etc.). The Company will provide notice to crewmembers prior to the beginning of any bid period in which paragraph 7 will be waived and detail the extent of the waiver.
