A method and system for generating a notification for a third party when a traveler is overdue at one or more waypoints. A traveler or other person specifies waypoints the traveler will pass during a trip. In response to the traveler beginning the trip, a latest arrival time is determined for the first waypoint. If the traveler has not arrived at a waypoint by the determined latest arrival time, a notification is generated for a third party. Conversely, if the traveler reaches the waypoint before the determined latest arrival time, no notification is generated. In either case, if there are remaining waypoints, a latest arrival time is determined for the next waypoint and the process continues.
