The booking form is not displayed

First of all, you need to check the Primary Pricing Category and add the price to the primary pricing category. You can check the Pricing category via Dashboard > Trips > Pricing Categories.

And then to add the price, you need to go to the trip edit page on the Pricings and Dates tabs to Add a New Package/edit an existing package.

You need to make sure you have added the price on the primary pricing category( i.e: Adult ) in the above case.

Note: You need to make sure that you haven’t disabled the booking form via Dashboard > WP Travel Engine > Settings > Display > Single Trip > Hide Booking form.
