Stryker is pretty accurate. The movement is based on our current staffing levels being below what we need to fully staff 65 aircraft. Our flying is down right now as we wind down the AA feed and prepare for the UAL spool up. Rumors abound about how much flying we will do for UAL, but as of right now it's only for 65 aircraft. You will find out, (if you didn't already know) management is notoriously tight lipped about specifics regarding the future.
Re:lines. Yes, 3 off 4 on is the norm for lineholders. 3 off 5 on for reserves. Typically reserves fly a lot although it fluctuates over time due to staffing. I would expect to fly a lot for the foreseeable future. Lines lately have been lower credit, 70-80 hours. With 14-18 days off. Again, due to the lower total block hours there are more sits during the day. Traditionally lines have been 80-100 hours with 12-15 days off. With some outliers.
Our CPP is rumored to be very similar to the other agreements out there and supposedly there is an announcement coming shortly.
