is there an itinerary template for pages

Searching the web for Pages Templates produces several results including this site:

https://www.template.net/editable/itinerary

There is also an App called "Templates for Pages - DesiGN." It is subscription-based and seems to have a 3-day trial period.

You can design and save your own itinerary template starting with a blank template. You might be able to open a Word template and save it as a Pages template, providing the Word template can be translated by Pages.
