I think it should be 1st come 1st served but I would like to see a window maybe every 4 hours for trips with a show within the next 4 days and 12 hours for trips that show outside of that. Then trips assigned based on PMU and time stamp. Anyone with a currrent BLG more than seat average plus 6 goes to the end of the line. The really important thing is all computer awarded and real time view of where you stand on the request and who is in front of you. Of course PMU hours should be only used once and done.
