I don’t know what methodology dera used to get these figures but sometimes people do bid reserve in significant numbers, so maybe that allowed some lines to go junior. If you take the seat seniority and assume everyone who can hold a hard line bids one, it is a very different picture. And of course composite lines are not lines, the scarcity of open time guarantees that.

In May:

DFE - 11/20/17 hire
NFE - 12/18/17 hire
MFE - 03/12/18 hire
OFE - 03/12/18 hire

Personally, I’m surprised to see Miami go so junior and so NYC so senior. Anyone can see though that in every base you are potentially looking at more than 7 mos of reserve on the WSCOD, and the day one gamble is still very much in effect and will rule your life for your first 2 years as an airline pilot.
