There are Two Places where it is possible to Delete a Trip:
1) The Trip Data screen. With the desired trip on the Trip Data screen and the cursor in the Start Date text field, press the F3 key on your keyboard. The current trip will be deleted and replaced on the screen with either the default empty trip or another existing trip for that customer.
2) The All Reservations, Daily by End Point, By Date, Trip By Landing, and Selectable Mailing List Reports. From the Report, select the Trip that is to be deleted and press the F3 key on your keyboard. If the report has any totals, the totals will NOT be updated to reflect the deletion.
