The flow is helping the company with retention and attrition a lot more than you think. A lot of people won't admit it, but they don't have any apps out and waiting for the flow. I'm talking junior captains too. The upgrade time is currently 2.3 years, short enough to help with FO attrition also. A lot of FOs are holding out to be a captain for the first time in their life and don't have apps out. Street captains and 6 month upgrade captains might have apps out but a lot of them would already of been hired and wouldn't of come to PSA in the first place if they had competitive LCC qauls. They will probably stay tell they have 1000 hours PIC, which takes 2-2.5 years on reserve. Attrition is where the company wants it. An increase from 5 to 7 on the flow would result in the same amount of attrition and more predictability for the company.
