This is great news.
For those unfamiliar with the story, when MassPort installed their own WiFi at Logan airport, they told all of the airlines that they had to pull their own internet access from their lounges as a violation of their lease and because it would disrupt the airport's service. Continental objected and took it to the FCC for clarification. This ruling says that airlines can offer their own connections. I don't know if any other airport has tried this, but its a win for the little person.
