I think most of us were expecting some WB CA slots this vacancy, but I was a little surprised with the sheer number of NB FO slots...which I assume is just meant to go to new hires over the coming months. Something I'm unclear on is the seeminlgly large un-balanced numbers. Taking into account the unfilled slots - ORD320 CA vs FO numbers are 269 CA and 334 FO....EWR737 is 594 CA and 483 FO....DEN737 is 558 CA and 380 FO...what's with the unbalanced numbers?
