Southwest has started offering in-flight Internet to pax: source

Amended to include Southwest's comment...

I have it on good authority that Southwest Airlines' crewmembers are encouraging folks to try out the Row 44 in-flight Internet system now installed on a Boeing 737.

"They do have one plane up and running with it. Passengers can try it for free," says a source with knowledge of the situation.

As mentioned in my latest video blog, Southwest has been doing its own testing of the system (which is apparently installed on a 737-700, registered N901WN).

However, a Southwest spokeswoman insists that the commercial trial has not begun. "We are not testing with customers yet," she says.
