UA lists the terminal maps of their "hubs and key airports". Other than UA's own hubs, FRA (LH), and NRT (NH), the only other one showing up is Boston Logan (BOS).

That's very surprising considering (a) UA doesn't have the traditional "shuttle" that goes to LGA/DCA, (b) UA doesn't have long-haul out of BOS, and (c) US Airways barely treat BOS as a focus city, if that much

Any explanations on this? Or just a fluke ?
