Does unplugging from the Internet make you or any of your customers break out in a cold sweat? Do they feel like they need to be working all the time because of staff cutbacks and the recession? Now computer resellers and their customers needn’t fear being away from their ERP systems due to air travel anymore. That’s because American Airlines is joining Delta in offering an in-flight Wi-Fi service.

American Airlines’ service, Gogo, is available for a $12.95 fee on some cross-country domestic flights and can be used on any Wi-Fi-enabled personal device a passenger brings onboard, including a PC notebook, a smartphone, a PDA or a portable gaming device, according to American Airlines.

Passengers can register for the service at the Gogo kiosk in the airport terminal or in-flight using their Wi-Fi-enabled devices.  Cell phone and voice over IP (VOIP) services such as Skype are not available, however.

The service is available through a partnership with Wi-Fi provider Aircell, which is working with several airlines to provide the in-flight Wi-Fi service. It works by equipping aircraft with antennas that connect with signals on the ground. The service will work for passengers once the aircraft reaches 10,000 feet. United Airlines is also working to add the service.
