Welcome to the world of iPAQ ownership!

One of the best freeware applications is from AvantGo. You can pick hundreds of categories to synch to your PDA including AA schedules. Compared to the AA timetable, AvantGo's advantages are that it is dynamic (if the schedule changes, the next time you synch, the new schedule will be in your PDA) and that it uses a lot less than 1M of storage for the AA info.

My 2 favorite applications, however, are Metro and Zagat.

Metro computes the shortest route between two subway stations in 170+ cities around the world (Paris, New York, London, Tokyo, any city with a subway) on PalmOs and PocketPC.

Zagat, of course, is the indispensible guide to restaurants, and is well worth the $20 to have most of the world's restaurants in your pocket.

Our family of 5 just got back to San Diego from London where we spent New Year's. $2000 AA airfare total for 5 people and we all flew F/J (thank you VIPOWs!). The iPAQ with Metro, AvantGo, and Zagat flew for free with us ;-) & made the time in London all the better.
