OK - As of this morning I am a brand new US CP (~platinum). I often hear of comping by OAs.

1. Do OAs comp and, if so, which ones?
2. Do they just comp status, or are any miles comp'ed as well?
3. What are the mechanics of comping? Do you call them, do they call you, how do you go about it?

Besides airlines, how about hotel programs? I am an HH diamond and PC Gold (former Platinum). Any reciprocal comping there with my airline/hotel status?

Maybe this is covered in other threads, but I couldn't find the specific info I needed, so here's a chance for the real gurus to show off their knowledge of arcana.
