I don't find all this excess capacity on UA on their IAD-Europe routes. I was on a MUC-IAD 767 flight that was cancelled. There was no room for us on UA or LH out of AMS, BRU, CDG, LHR, or FRA(all flying) that day and no room out of FRA, MUC, CDG the next day. We got the last two seats out of BRU. We have only had 3 trips since late Nov to Europe, but the UA planes out of IAD have been very full.
