I'm trying to not be arrogant when I say this - for UConn fans it's a rare opportunity, for everyone else it's a once in a lifetime opportunity. If you can make it work, you should do it.
Actually, both Dallas and Phoenix are AA hubs....about a dozen flights a day. It won't necessarily be cheap since as far as I know there's no real competition on that route, but if you start looking now on Travelocity, Orbitz, etc (and AA>com) you may be able to find something. Here's the listing for tomorrow - it will give you an idea of the flight times which ought to help you plan. The times change a little on the weekends.
The formatting/spacing seems to get lost - sorry, so it's flight number, departure time, departure gate, and arrival time (local, but using 24 hour clock) and Airbus (320) or the once-a-day Boeing (737).

Anyway, if you do decide to go to both tournaments, at least with the direct flights you wont look like poor Jon Samuelson...
As an aside, 448 from Dallas to Phoenix was the first flight I ever did after I was hired, so it's a little special for me. But as it is I will probably be stuck up here in the Land of Steady Habits for the Final Four.
And, while I cant speak for the board as a whole, I feel that one of the things that makes this board special is the participation of our foreign visitors. Even if it gets heated once in a while... so thanks for being here, and good luck!
