From what I understood, the Nov bid was more to take advantage of SIM availability through FEB2020. Thats why no 330 positions, SIMs were full until spring. With the increased hiring announced several months back, additional positions needed to be created as well, which sustains any staffing adjustments system wide. The Jan/Feb bid will be a continuation of the logic behind the Nov AE, but with MAR-MAY sim slot focus.
