You heard right, folks. American Airlines is planning to open up the world wide web to passengers on board an unspecified round-trip flight from New York’s John F. Kennedy International Airport and Los Angeles. The Gogo service, provided via Aircell, will be free for patrons tomorrow, but will eventually run users $12.95 for flights greater than three hours and $9.95 for trips under said threshold. We’re also told that more trials are expected to get going on flights between New York and San Francisco and New York and Miami, though no time frame is given for when the service would escape the beta stage and hit mass implementation. Additionally, the Gogo system is supposed to “prioritize the flow of data so that passengers downloading movies or large documents won’t prevent other passengers from getting their email,” so don’t expect to use that excuse for not sending in those Q2 close reports.
