It's amazing to me when an airport doesn't have free wi-fi. I know it's another way to make money, but in an industry that goes bankrupt every few years anyway, why not give fliers golden EVDO cards upon entering a carrier's terminal?
Wi-fi Free Spot posted a list of airports with free wi-fi. Biggies like Dallas and Chicago (Midway and O'hare) aren't on the list - which is a shame. In fact, most airports with free wi-fi are smaller (which on one hand makes sense - expense - and on the other hand does not - resources).
Hit the jump for their best tip to find free wi-fi at any airport. And let us know if you have any wi-fi tips for travelers.
"A Pilot has told me that most FBO's (Fixed Base Operators are the service stations for corporate aircraft) which are located at almost all airports large and small are offering unrestricted WIFI service in their facilities. Go to the general aviation facility for any airport, ask where corporate aircraft arrive and depart, go into the facility and ask them if you can use the WIFI capability. Most of these FBO's have waiting areas and some provide separate computer rooms (like a large phone booth) as well as the ability to print."
