Average line in MEM is 86 hours. There is always open flying that you can pick up so long as you don't go below 10 days off. So if you bid and are awarded a 83 hour line with 14 days off, you can pick up a 4 day (or two, two days or a three day and a out and back or whatever combo you can come up with) in open time and get premium pay (time and a half) for that trip. That is when you make the $$.
