So I’m currently a couple thousand feet up in the air on a Virgin America flight to San Francisco from Boston and Google are doing this cool thing where they loan you a Chrome Book for the flight, apart of this, you get free wifi on the Chrome Book, whilst on any other device you need to pay like $12.95. I figured out by faking the User Agent to be that of the Chrome Book, you can get free wifi.
TL;DR : Set your browser User Agent to this:
Mozilla/5.0 (X11; CrOS i686 1193.117.0) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.66 Safari/535.7
On Safari do it like so, make sure the Develop menu bar item is enabled (Do this in the Advance tab in Safari Preferences), then click on the Develop menu, then into User Agent, click other and copy and paste in the above browser agent string.
This tricks whatever is handling the wifi into thinking your computer is a Chrome Book and gives you free wifi as apart of the programme they’re running with Google!
Enjoy my friends!
