Southwest Airlines plans to add WiFi in the second quarter of this year, the Chicago Tribune reports:

Southwest will install equipment on about 15 aircraft per month initially and gradually increase that rate to 25 planes per month. It estimates that Wi-Fi will be available on the more than 540 planes in its fleet by early 2012.

In little more than two years, Internet service has become widely available on flights within the U.S. Itasca-based Aircell, the leading Wi-Fi provider, has installed its Gogo service on about 700 jetliners and earlier this month raised $176 million to further fuel its growth.

Pricing info hasn’t been released. How much would you be willing to play to websurf on a long flight?
