I'm not sure what 'BIS' means but I flew about 250K actual miles last year and due to a recent job reassignment am now flying at a rate of over 500K actual miles per year. Most all of those miles are on Star Alliance carriers and I'm currently putting all those miles into BD's FFP. With bonuses that will come to way over 1,000,000 miles per year just for flying. I fly a R/T long haul once every 1 or 2 weeks. All my flying is for business and have no time for leisure travel at the moment but am just hoarding my miles for future leisure travel when my job will allow it.
