LOL.

My favorite is JHM, although now that HA has resumed service there, it's at least
conceivable. And, of course, good luck finding a WP flight anywhere...
I thought that the Continental Connection flights that Colgan operated in the northeast -- in the early 2000s, I think? -- might have included BUF, but I can't find any evidence of that now. (I did find a mainline UA BUF-ROC flight from 1999 though.
Still, keep in mind that the routing table only governs transfers; so, if you can find a direct flight from BUF-LAS, presumably via ORD, you'd be able to use it.
