We have a 3 week trip all by train scheduled in mid-September. We are taking advantage of as many panorama trains as possible. We have purchased our seat reservations for the: Gotthard Express, Bernina Express, Glacier Express, and Golden Pass trains. We are going to purchase the 1st class, 15 day consecutive Swiss Rail Pass and we'll figure out our last 5 days transportation later, as the Swiss Travel Pass will cover those train dates. We purchased the seat reservations online without the Swiss Travel Pass, knowing that we were going to purchase it later.
We haven't purchased a ticket on any of these trains because we believe that our Swiss Travel Pass will be that ticket. Are we correct on our assumptions? Or should be purchase the Travel Pass now and use it to pay for our tickets now? We are really confused!
