Alaska Airlines (Seattle/Tacoma) is now offering Aircell’s Gogo® Inflight Internet service on more than half its aircraft, including all 55 of its Boeing 737-800s and 10 of its 737-900s. The service will be available on the airline’s remaining two 737-900s by the end of July.

The airline is partnering with the Alaska Airlines Visa Signature® card to offer passengers Inflight Wi-Fi free of charge on flights through July 31, 2010. After July 31, the Gogo service, currently available in the U.S. lower 48 states, will be offered to customers at a cost of $4.95 per flight and up, based on length of flight and device used.

The airline’s remaining 737-400s and 737-700s will be equipped with the Gogo service by the end of 2010.

To ensure the service is available to the airline’s namesake state, Aircell will expand its network by early 2011 to provide Gogo Inflight Internet service on key routes to, from and within the state of Alaska.

Aircraft equipped with inflight Wi-Fi have a Wi-Fi symbol located outside the aircraft’s boarding door and information about the service located in seatback pockets. Gogo is available above 10,000 feet, following an announcement approving the use of portable electronic devices.
