In a bold move, Southwest Airlines has promised to go fleet wide with the installation of Row44's In-Flight WiFi service which competes with AirCell's one year young GoGo service that is installed on the likes of Delta, American Airlines and fleet wide on Virgin America.
The difference between the two competing services is based on how the planes IP transponders talk to the Internet. Aircell uses a technology that connects to ground stations. Row 44 uses KU band satellites.
As an "A" List flyer on Southwest, lately I've switched over to Virgin America for short hops and cross country flights because of the GoGo service being on board. The deployment of Row 44's technology will sure get me back on board Southwest more often.
