IAD-MUC for New Year's Eve in Germany. Location chosen based solely on EQMs (furthest location in Europe from IAD) & "cheap" last minute W-fare (under $700). I'll end up with 100,220 mi.
Bonus: Kicking off the '06 requal. with 4,200+ miles from the return flight.

This requalification is a vicious cycle isn't it? It never ends ... always chasing that 100K and just when I get there, I have to start all over!
