About half have flowed. The last of the 824 should flow sometime around the end of next year to March/April of 2017. The flow continues at 50% until the end of the "protected pilot group" Oct 2011 hires then it goes to 35%. There are only 100 - 200 pilots on the seniority list hired since Oct 2011. Based on AA/US retirement forecasts, there should 200 - 250 flows per year at that time. Someone hired today, will flow about 6 - 8 months after a Nov 2011 hire.
Inky13 posted a nice breakdown of it in one of the envoy threads.
