All these years and flights and I have never been lucky enough to have WiFi on a flight. Interestingly almost everyone else I know has experienced in-flight WiFi already. Thanks to Virgin America for their awesome GoGo Wireless service. Here is a speed test from the air on the way to Vegas from JFK.
It costs $12.95 and interestingly my coworkers and fellow passengers tell me checking online indicated this flight did not have WiFi meaning you too can be surprised by wirelss broadband in the air.
