It seems like everyone is hopping on the in-flight WiFi bandwagon these days, with American Airlines only the latest to offer the desirable service, joining the likes of Lufthansa, Qantas, and others. For its system, American Airlines is relying on the expertise of AirCell, which is promising to get things up and running on at least some flights sometime next year. Initially, the in-flight WiFi will only be offered on American Airlines' fleet of Boeing 767-200 aircraft, which primarily fly transcontinental routes. From the looks of it, however, the service won't be a freebie, with American Airlines saying it'll announce the cost of the service at the time it's rolled out.
