im not a big fan of massive displacements. They disadvantage the pilots that are not in closing BES whom are patiently awaiting upgrade or wb. For instance, the junior position on sfo 787 ca is 3000 (due to fence). The junior position on the 777 sfo is 2000. 2000 is realistic number for holding wb Capt in sfo. You will see a lot of 2000-3000 seniority pilots bump into sfo. The end result is that more pilots who are too junior for the position will be taking wb Capt slots thus keeping the more senior pilots whom aren't subject to displacement from being awarded in a future vacancy.
