The "Mile High Badge" is nothing more than a digital token you can use to celebrate your location-based conquest. But the Foursquare-Gogo team-up suggests that in the future, mobile phone checkins may have an important place in the sky too.
Gogo Inflight Internet is available in the United States on Air Canada, AirTran, Alaska, American, Delta, United, US Airways and Virgin America. A la carte, Gogo service costs around $10 per flight, depending on the airline and the destination. The provider also sells service by month, in six packs and as 24-hour passes.
