DESTINATION: The final stopping place where the passengers end his/her journey and this is also a terminal point in the routing is considered as a fare construction point or a fare break point.
INTERMEDIATE POINTS the points falling in between the origin and destination or may be called as via points or transfer points are intermediate points. It may be divided into two again

INTERMEDIATE STOPOVER POINT in this the passengers take a break and his next connection is after twenty four hours of his/her arrival. The stopover is intentional and is indicated on the ticket.
