The 2005 flows will go to 2011 flows in about 2 years (when the Protected Pilots finish flowing). Why? How can 6 years of hires flow in 2 just years?

Simple answer. They are a part of the 'lost decade' when there were very few hires. So there are not many pilots hired in those years to flow.

As I have said on other threads, just a few years ago, pilots were flowing with 25+ years at a regional (most Envoy/Eagle, some with other regionals then Envoy). Why? Because up until a few years ago, AA was hiring few pilots. Heck, until 2016 they still had TWA pilots on furlow.

My how things have changed. That change is going to accelerate over the next few years, even more because retirements are increasing at the majors.
