FWIW, life on the 767 can be a bit different. We don't have the varied route structure the 747 has, so although things can and do change plenty ahead of time, once you get going, you'll probably stick with the plan, unless you've got a long layover somewhere really nice.
Looking back, my sked looks like the ones posted, but looking ahead is different. JFK 767 guys have been bidding reserve lines since october. Maybe we'll get lines of flying to bid for when AMC picks back up, but who knows. CVG and LAX have set schedules, so those bid packets look more normal.
