IAH 737 FO bid awards
I am having trouble understanding something and was wondering if someone could straighten me out. I notice that there are only 452 IAH 737 FO spots posted. Looking at PBS, there are currently 671 IAH 737 FO's. Are there like 300 vacancies that have gone unfilled in this BES, or does this mean some of the flying is getting moved out of houston or to another fleet (airbus??). I'm having a hard time getting an idea of where this puts me as I am basically the same percentage in base that I am now if there are only going to be 452 IAH 737 Fo's. I suspect this isn't right and there are several hundred vacancies that have gone unfilled. What have I missed?
