Today I was holding short Uniform, ready for takeoff R05, when i'm advised by tower that I will be #2 on departure... surprise surprise, Precision is taxiing out. Their 733 is coming from terminal 2, whereupon it takes a left on Papa, taxis R14 to R05 and proceeds to backtrack R05. Here I am sitting and wondering what's going on? Why they didn't just taxi down Papa to the end is beyond me. I could have easily departed while they are taxiing behind me on Papa, why on Earth do they insist on backtracking the active runway and delaying departing traffic when there is a perfectly good taxi way called PAPA? Afterwards I'm told by tower that the reason for Precision as #1 is that because we are both heading south and they want to avoid conflicting the traffic. Moroni is track 140, Mafia is 155... Last time I checked Precision will climb to 4000' before turning on course... a caravan flying VFR can make an immediate turn. There's no reason for this nonsense. Precision gets a kick out of screwing over other traffic and clearly ATC in on their side. I urge other pilots sharing the sky with Precision to post their experiences on here.
