I'm curious if anyone has ever flown a domestic MR with BOS as intermediate connection point.

For example, it is well known that UA allows lots of connections, and it is common for UA MRers to 'bounce around' the west coast, doing things like BOS-SFO-SEA-SAN before returning to the east coast. Has anyone ever flown such an itin via BOS?

I'm curious because now that I don't live full-time in Boston, it would be useful / interesting for me to route trips back that way. But I've never been able to get a flight routed back there. For example, say I want to do DEN-IAD. Has anyone ever gotten DEN-BOS-IAD? The only carrier that I can imagine doing this is US, since I have seen (and flown) some stupid BOS-BUF-DCA-XXX itins before when I was too cheap to do the one-stop.
