More Airports Tell Drivers Just Where to Go -- to Get Parking

The push to deliver current parking information to travelers comes as airports are increasingly looking to differentiate themselves from competitors: other airports and off-airport parking lots.

*Radio and telephone. Many airports stick to the old technology -- low-power radio broadcasts on airport property, or a call-in number. Milwaukee and Fort Lauderdale are among the airports that broadcast by radio.

Phoenix, San Francisco and Burbank, Calif., have a phone number for parking information that is answered by a real person. Minneapolis also plans to introduce an automated parking hotline this month.
