There is an art to dropping trips. Learning the bad day worse day trade is difficult but is key to dropping trips. I was able to drop a Christmas day (O dark thirty) trip by picking up some worse day trips earlier in the month and combining them with my Christmas trip to get a net bad day vs a worse day scenario. Also not to insult you but are you ending your bid groups with award work L--? Someone correct me if I am wrong but that tells the solver that you want it to give you the least amount of trips/work that will meet your constraints and is a legal line. Anything higher than L-- it could give you extra trips and extra hours to make someone junior to you better off. I'd also add these are unusual times. 90 hour lines are not normal and is being driven by an increase in rsv coverage so the company doesn't have a repeat of Jan if there were to be another wave of the Rona. I'd be surprised if that were to continue once the IOE backlog works itself out and rona case loads drop, I'd be willing to bet that the extra rsv coverage that is driving these high mpg lines will return closer to the normal for your fleet/domicile.
