USA Today | For years, one of the top if not the top amenity on many road warriors' wish lists has been free Wi-Fi at the airport. Slowly but surely, it's happening.
Take a look at the USATODAY.com Airport Guides, airport websites, and various commercial and user-generated Wi-Fi directories. You'll see there are now hundreds of U.S. airports offering travelers complimentary wireless Internet access.
San Francisco? Free. Orlando? Free. Seattle, St. Louis and San Jose? Free, free, free. Washington's Dulles and National airports? As of April, 2011, free as well.
