Free and fast in-flight WiFi may be an unrealizable dream, but free in-flight Facebook? Wish no more. As of today, seven airlines are running a promotion with Gogo internet to bring your in air Facebook dreams to life. The airlines include Delta, AirTran, American, Virgin Atlantic, Alaska, US Airways, and United, who with Gogo now offer internet on 1,100 commercial and 5,000 private planes. It's unclear how long the promotion will last -- nothing good lasts forever -- but get in there while you can and do a few status updates, maybe check out your friends' awesome Groundhog Day 2011 links.
