Tedeman, I also use Expedia's
Fare Tracker which I now believe is what
Pacha was actually referring to in his post above. I use it so seldom, compared to Travelocity's
Fare Watcher that I forget about it. It is useful and one more tool to assist in maximizing miles.
Another resource I use is
Deals & Destinations OneTravel.com Savings ALERT! from
www.onetravel.com . I also have signed up to receive, usually every Wednesday via e-mail, the weekend internet-only airfare specials from various airlines.
