When I look at the route Chur to Tirano, Italy, on SBB, the prices differ, either by time of day or itinerary or both. If I want to plan on a specific time/itinerary, except for an increase in rail prices by SBB, can I count on the prices to be the same every day? I realize I need to double the fare since the fares noted are assuming a half price card. Given that and the fact that there are two of us, it does make sense, within reason, to choose a route/time that has a lower fare. Also, when I purchase a ticket, it will have a specific itinerary, but is there any reason why we can't stop for an hour or so at a connection if something looks interesting?
EDITED TO ADD: It looks like if I take an 8:32 train, I can pay less (63 Swiss Francs) and get a nonstop train, that is a Panorama express. (Though I'm not sure that a PE train vs. the "regular", IR train, gets me anything more if I am not in first class), vs. a train that leaves at 9 which was about 17 Swiss Francs more
