Depends on the company… American has more retirees, I think they have 900 a year, delta has slightly less, United has 4 to 600, Southwest has slightly less.
so yes, you do lose some by attrition, and you can’t cut 1000 pilots overnight... but it also depends on what the airline’s desired end state is.
So if United wants to come back as a domestic airline, with no widebody flying, and much smaller, then those retirements are really not an issue because those jobs that are in existence now, will not be in existence in five years (again depending on the end state). If United’s end goal is a status quo, then yeah those retirements will definitely affect the duration.
but
@wiseguy04 whole furloughs aren’t meant to be sustainable, many people were out for 7-8 years.
Some were furloughed twice, 9-11, and 2008
