Frequent fliers can now rely on their PDAs for more than just scheduling meetings and making calls. You can even organize the details for your next trip.

With the Blackberry or the Palm Treo, you can access the Orbitz mobile service and check hotel vacancies in 20 U.S. cities for the same night and call the hotel to confirm your reservation by just pushing one button.

If you type the three-letter code of your airport into the FlightStats application, you can find out how long the airport’s security line will be, based on data from the Transportation Security Administration.

The HP iPAQ Travel Companion features street map software from TomTom, making it easy to get around in unfamiliar cities.

Other features on these PDAs will help you translate a language, check the weather, find restaurants and even find places to dance – that is, if you have any energy left after all that.
