Hi Jaredm / Lucas,
It's an interesting point about Transfer Ticket routes. In the winter we usually use Transfer Tickets as our Ski Passes serve us well during the rest of the holiday.
We often travel between Zurich Airport and Interlaken Ost via Bern and back by the Brunig route and Luzern. It's shorter by one route but quicker by the other and our tickets have never been questioned. Nowadays you don't have to stamp your tickets with the time and place at the start of your journey, just write in the date, and we've often stopped for a break on the way but not, of course, overnight.
Jaredm. At one point you say you are travelling from Interlaken to Como in one day but then you say "stopover" in Luzern, which Lucas has, not surprisingly, taken to mean overnight. It makes a big difference.
If you do mean overnight in Luzern you will need to buy a ticket from Interlaken to Luzern (Brunig Pass route recommended) and use the Transfer Ticket for Luzern to Chiasso. If it's only a few hours in Luzern your transfer ticket will take you all the way from Interlaken via Luzern to Chiasso - it's about 4 hours and is the route given by the SBB timetable app. In either case, you will need to buy a ticket for Chiasso to Como - it's not very far.
Hope this helps. Sorry, but with the aid of the links Lucas has given, you'll just need to do the arithmetic. Have a good time.
