I have used the 'Flight Tracker' Widget on the Mac. Not much use when I go to pick her up on arrival, however. Our airport has a very, very conveniently placed "Cell Phone Lot" for people waiting to meet someone. They they/she arrives at the gate, she calls and I meet her at the arrival doors just as she comes out!

might be interested, however, she plans her flights very precisely and watches for the best time to make the purchase (usually for her and another lady who has trouble even using a cell phone...) and the hotels are either provided by her host or pre-arranged for a convention somewhere.
Still, FEE is one of my favorite prices!
