Sorry to bump an old thread, I know alot of people hate it.
I was going over some old threads and found this one, incase anyone is still interested.
http://skyvector.com/ SkyVector provides Sectional, TAC, and Low/High Enroute charts. Boston is located under the NY Sectional. The Low-Enroute charts will have all of the Victor Airways (V141, V431, etc). The High-Enroute charts will show the Jet airways (J97, J121, etc).
You can also see some of the Victor airways on the sectional. Hope this helps someone, SkyVector.com is a great resource
