since we all gripe about vouchers vs free Tix : here's an interesting printout from my trip sin-nrt-sfo-mco. Sin-Nrt was wide open but nrt-sfo was tight and sfo- mco was f2=y1. In singapore I asked to be put on the VDB list, on a light day, hoping to be able to re-route "without" a fee, to get to mco 3 1/2 hrs early. Sin TA printed out the following blue card attached to my BP.

This is what it say's on the blue printout.
