I picked up two face value tickets yesterday, but I'm part of the Tyee Club (season ticket holders who donate additional money, i.e., boosters) so not sure if that is available to other season ticket holders. We were all hoping for Glendale, as that is a quick and cheap flight. Though we'll lose fans because we have to travel all the way down to ATL for this game, we'll represent well. I've gone to a ton of away games (including UW at LSU), and we always hear, "you folks brought a lot of people." I think you'll be surprised. We pretty much knew LSU was gonna kick our arses, but we still went down there (but NO is a better draw than ATL to most Husky fans).
We'll bring at least 15K, and I wouldn't even be surprised if we brought 30K. But the distance is pretty crazy and flights non-stop to ATL from SEA are $1K+, so that will weed out the younger crowd....
I've been travelling to UW away and bowl games since 1991. I've yet to attend a game where our area wasn't packed with Husky fans (but I don't go to pac-12 championship game; saved my money for this game as most Husky fans knew we'd kill Colorado, which we did).
