American Airlines offers Internet Service

For $12.95, passengers on AA flights using its Boeing 767-200 will be able to surf the Net, check e-mail, instant message and access corporate VPN accounts using the system by Aircell LLC.

The ground-based system – called GoGo – won't enable any voice-based functions.
American says it will test GoGo on its fleet of 15 767-200s, which are used primarily on transcontinental flights, for three to six months.

Assuming everything goes well, the carrier may expand to the rest of its fleet.
