This is also the first month guys 6 months senior to him were able to hold a hard line in ORD. The 11/18 hire will be back on reserve next month when ORD 145 loses 20 lines, and all the TDYs senior to him go back to ORD.

There is a empty spot on the ORD 145 FO seniority list. There are only about 20 in that status hired from 2/18-8/18. So, a reduction of 20 lines could conceivably reverse the junior lineholder date 6-9 months.
