I hear you. I do not believe in "first come first serve." That's what everyone says, but not what I observe. I have been #1 holding short at SLC with no one else around and held while the ENTIRE PUSH comes off the terminal and departs. After the last airliner leaves we (and the rest of the corp planes) are allowed to takeoff.
Or...A Citation X and a CRJ both going from LEX to CLT, both number 1 for takeoff from opposite sides of the runway. Which plane do you launch first, the Pinto or the Ferrari? You guessed it. The Pinto (CRJ), goes first while we are speed restricted the entire way and then vectored 40 miles past CLT to let a few more CRJs get in front of us. It turned a :30 min flight into 1:00+.
Or...Climb/speed limited behind a plane climbing at 500fpm (an slow to boot) when we need to get to altitude to make max range projections. We plan (try to plan) on at least reaching FL410 in the first :30
I could rattle off stories like this all day. The point is, if you don't have a name stenciled on your plane, you go last. Typically we are asked to decrease cruise speed 15% to "get in trail." Would ARTCC ever think of asking a DAL 757 at FL410 to slow 15% to .64 - .68M to get in trail???
