Bid was just awarded today. Almost all vacancies were on the 737 SFO/LAX/EWR , a handful on the 756 EWR/SFO, 320 SFO/LAX.
Everyone should bid the 737 unless you don't have a choice! You can always bid up when the opportunity arises. The 756 WILL NOT get you to any base quicker. If you do get the 756 not all is lost recently SFO has been going unfilled but only a couple a time, not in big numbers.
SFO/LAX will be easy to get, If you don't get it on the drop you will get it for sure on the next bid. IAD/ORD is going to be tougher, its not very senior but there has been no unfilled slots in a while, probably 1-2 vacancy bid cycles. IAH/DEN/CLE enjoy the commute.......
