Thanks. Using your example I think I've finally figured out how to push the ITA software to do what I was looking for.
A couple of related questions.
1. How can I tell if a route is valid if I'm trying to push beyond ITA? I know I was able to book cheaper last DEC coming back (although with a slightly different city) ORD-ZRH(via IAD)-(train to MUC)-MUC-SFO-SAN(1 week LO)-ORD and the fare was cheap. I'd like to do something similar this time but I can't seem to coax any of the systems to route the whole thing (nor do any of them seem to have enough "slots" to book a detailed stop-to-stop route.
2. Breaking up the itenerary? I see that there is currently some bonuses for UA on flights departing IAD. I'm assuming they have to start from IAD, not simply be a connection. What do I need to do/ask to ensure the correct ticketing? I'm thinking I'll get more miles (althought not EQM) for the bonuses if I can't figure out how to get to ZRH via a the west coast
