Is there a one day travel ticket?

We (2 adults) are traveling in Switzerland for 5 days. We have already purchased the 4 day travel pass. On the 5th day we need to travel from Interlaken to Zurich & to Zurich airport to get our flight home. What is the best kind of ticket should we purchase for that day? Thank you for any suggestions.

Hi jypcjo, welcome to MySwissAlps!

You can buy a regular point to point ticket in Interlaken, or possibly a Supersaver ticket, if available.
