I've dispatched FAR 121 planes into ASE, so here goes...
A. Land on 15, depart 33 only. For performance purposes, you simply have no other options. If you have to blast off with a tailwind, so be it. Yes, you do leave people behind when you do that, no way around it. I had one airplane that had a 15kt tailwind restriction, and I have had to use it several times at ASE, and yes, you do leave about 1/2 empty when you do that!
B. CRJs must configure flaps 30 and gear over DBL, so as to allow the crew the ability to devote complete attention to the approach. You set final landing flaps about 5 miles past DBL.
C. With the Special to 15, 121 approach minimums are 3 miles, with an MDA of 1043'/8780. The Special to 15 provides straight-in minimums. The visual requires 6000-6.
D. During the winter, unless it is SEVERE clear, you always carry an alternate to ASE - either GJT or DEN, but you always carry an alternate, with additional hold fuel for holding over DBL since ASE gets busy in the winter.
E. The missed approach point is 2.5nm prior to the arrival end of the runway.
F. The missed approaches are hairy, requiring specific bank angles, and speeds. Exceed the banks or speeds, and your bird will hit the cumulogranite.
