The flow is nice because it guarantees movement each month. Every single month, "X" number of pilots leave for a legacy.
At PSA, we have been sending more pilots to other legacies every month than we are to AA. Despite the flow, we also have pilots that are getting selected to interview at AA outside of the flow.
We have sent more to Delta in the last 3 months than we have AA through the flow. We have also sent pilots to United, JetBlue, FedEx, UPS, and Spirit. That is in addition to the flow.
Flow in addition to regular attrition is a great combination.
