Flat fare from point of boarding

In this case, any passenger boarding at or near the outer terminal pays the full fare for the route irrespective of where (s)he alights, but passengers boarding along the line of route are charged a lower fare to reflect the shorter journey that they can make.

This fare structure is common where no ticket or other fare validation is issued at the point of sale, and prevents any potential for overriding fraud by passengers. Clearly such a fare structure is most equitable when most passengers share a common destination, or set of destinations, at the end of the route, but strongly disadvantages those who alight in its early part. The operator can also benefit disproportionately from seat turnover as a result of passengers not traveling the full length of the route and their place being resold.
