Its actually called RPC.....
And no I don't think anyone is advertising for charters or cost shares. Reading the above it seems to me that people are only advising around about how much it would cost to cost share...
Then again 12 seats... ya can't cost share that many???
Then agian it could just be a private flight where everyone pays $1000 accomodation for the privaledge of sleeping under the wing. After all aircraft make dam expensive hotels...
