Being online while in the air is quickly becoming more commonplace for travelers. Following a successful trial run and small roll out last year, American Airlines has announced it will expand its in-flight wireless internet service to include 318 of its domestic MD-80 and Boeing 737-800 aircrafts, up from the 15 planes that currently offer Aircell's GoGo service.

The wireless broadband service will cost laptop users $12.95 on flights over three hours, and $9.95 on shorter ones. Customers using handheld devices will pay $7.95 regardless of the flight's length. Delta, Southwest Airlines, and other carriers are also testing Wi-Fi access to create a new stream of revenue while making flights much more enjoyable.
