How bout the alternative all those guys had, NO opportunity to upgrage..... Does that shed some light for ya?
Not really.
Especially the part about how a West pilot who never, as well, would have had an opportunity to grab a left seat in PHL on an International wide body provided by a retirement on another seniority list.
Maybe you West guys think United owes you all their 747-400 Captain upgrades? Delta 777 too?
