Yeah, especially if the team is from the East like Buffalo, or New England. That's a long flight to get to Seattle.
But nothing beats Arrowhead. I also like watching Seahawks games because they play in rain and on grass, so its all muddy and shit. Really fun to watch. Another reason why I hate the Superbowl being played in warmer states. It's stupid, football is meant to be played in the bad weather.
