Make travelling less stressful with free WIFI from Skype. Until December 27 2011, The fine folks at Skype are offering you an hour of FREE WIFI internet at more than 50 US Airports. All you need is a free Skype account and a Windows, Mac Skype application (or IOS Skype WIFI App).
You can read the Skype blog posts and get a list of participating sites here.
In years past, we have seen Google offer similar gifts (but alas, not this year).
