I have purchased 4 eurail global passes for my family, but I need help booking my seat reservations for the itinerary listed below and the Eurail planner app doesn’t show routes more than a couple weeks out.
July 20 Varenna, Italy to Zermatt Switzerland
July 22 Glacier express from Zermatt to Chur Switzerland
July 23 Chur Switzerland to Salzburg Austria
Thanks. Stephen
