The following are field parameters for requesting miles. The purpose of the Mileage request is to allow the host application to retrieve point-to-point miles. This type of request could be used for a quick mile lookup from a host inquire program or for running several stop-off points in a batch environment. The host dispatching software could generate this request when a new trip is established.
