The junior man in the 18 May 2015 is now sen. # 4149 . The junior man in the 7 Dec. 2015 class is sen # 4278 . That's 129 numbers below May in 2015 . The 6 Jan. 2016 class had 33 pilots . A new class starts in early Feb. . These numbers come from Positive Rate Weekly . If you count the 8 in the May class that's 137 hired in 2015 from May through December . Don't know how many were hired in 2015 before the May class. Also , not sure what it may mean but when the new sen. list came out in July 2015 the bottom guys moved up 165 numbers .
