This morning Google Flights found me a deal and I jumped on it; PDX-ORD-ZHR-FLR / FCO-ZHR-ORD-PDX. 1st/business for $2k less than what United's and Delta's web sites are currently offering. The "Book with United" link actually worked! Also, I was able to plug the United PRN into Swiss Air, get the Swiss Air PRN, and choose seats. (Free, but I didn't bite for the 'throne" seats, which were $164 extra!)
Outbound I have 2:10 at ORD to get from Terminal 1 'C' gates to Terminal 5, and a 2:00 connection in Zurich. Unclear what the layout at Zurich is and cannot find a clear reference online. ORD looks like take the tunnel to main terminal 1 and get the train to terminal 5?
Inbound I have 1:40 in Zurich. Unclear if that is too tight or not. I've seen itineraries with 0:40 in Zurich, which would scare me.
