After pretty much giving up on there being room on the lone Delta US to Zurich flight, they called our names at the last minute and we were on our way. About 9 hours later we were in Zurich. *** The Swiss rail system is outstanding by all accounts except for making it easy to figure out the cheapest way to get from point A to B to C to D over the period of several days. I spent a lot of time before the trip trying all the various combinations of unlimited travel passes, 1/2 fare passes, and other pass types and it ultimately seemed to work out about the same cost so we bought a 4 day "flexi saver pass" which could be used for any 4 days in an 8 day period. Fortunately the train rides are incredibly scenic which made the $400 cost easier to swallow.
