1,000 overstaffed? When? Right now? This fall? Next spring? Retirements AND when the comparison is being done matters. Peak summer vs October? That's probably a 15% (?) percentage reduction in flying which is 2000+ pilots. October has always been the best month to bid reserve and hope you don't get called. Details matter on if the alleged 1,000 pilots overstaffed is true when is the stated time period and compared to what?
Retirements wil eat into that which is a great furlough protection plan.
Historically 5% below you gives you protection from small furloughs and 15% below you on the seniority list gets you big furlough protection. 9/11 the worst furloughed about 25%.
