You can go to ALV or max reserve +15 on a yellow slip. After that any pickup would have to be on a GS.
If you hit ALV/Max Reserve you are done if you do not have a yellow in.
In either case call Scheduling and have them show you full for the month. You are done if you are within two hrs of ALV
Boeing wining that contract means that the 764 line will remain open and they may want to give a few "deal" on some jets.....
