Boingo Wireless now includes Logan International Airport in Boston in their roaming plan: Boingo offers a flat-rate monthly fee for unlimited hotspot use at most locations in their aggregated network; a few international hotspots have additional fees as does Connexion by Boeing. Boston has an independent operator that doesn't have a national roaming profile, and Boingo is the first no-roaming-fee partner I'm aware of that has struck a deal with Boston.
