Also, once the flow/ssp/whatever you want to call it increases this summer, the number leaving each month will increase even more. This increase has already been increased, and is supposed to be 10% of the pilot base each year. During the initial negotiations, it was 48 per year, as the pilot group was about 480 people. With a pilot group of 1000 now, it should be 100 per year.

I would expect the attrition numbers to stabilize at 18-20 per month, with an occasional high of 30.
