Abstract: A travel plan emergency alerting system is adapted to receive, from a user, user information and trip/alert information (including at least an expected time of return from a trip and contact information for an emergency contact person). The system is adapted to determine, based at least in part upon whether alert deactivation information has been received, whether the user has returned from the trip, and, based at least in part upon the trip/alert information, whether the expected time of return has passed. The system generates and transmits to the emergency contact person an alert message if the expected time of return has passed and if the user has not returned from the trip. In some embodiments, the system also includes a telephone interface through which the alert deactivation information is received. In some embodiments, the trip/alert information and the alert message includes a recorded message in the user's own voice.
