How Long to a Captain Upgrade?
Sometimes the time to upgrade can be the tie breaker for which airline to pursue employment with. If an upgrade at regional X is twice as long as regional Y, regional Y could be the go-to airline even if its pay and other factors are less desirable. A faster upgrade means more pay and valuable PIC turbine time (if time-building for career advancement) more quickly.
Keep in mind that these dates can change rapidly when an airline is experiencing rapid growth or furloughing pilots, so don't take the figures as gospel. They're just one more tool APC provides to help you make a better career choice.
