Method, computer program, and system for pushing flight information to passengers

A computer program stored on a computer-readable medium for operating a host computer to automatically notify passengers or agents of changes in status for airline flights, the computer program comprising:

• a code segment for receiving passenger reservation information from airline passengers or agents of the passengers, the passenger reservation information including a request for automatic flight status change notification information for an airline flight a passenger is reserving;
• a code segment executed by the host computer for receiving and storing in a database scheduled times of departure or arrival for substantially all U.S. airline flights departing or arriving within a certain time;
• a code segment executed by the host computer for receiving and storing in the database any updated times of departure or arrival for the flights;
• a code segment executed by the host computer for comparing, for each of the flights, the scheduled time of departure or arrival to the updated time of departure or arrival;
• a code segment executed by the host computer for flagging records in the database corresponding only to flights in which the updated times of departure or arrival vary from the scheduled times of departure or arrival by a predetermined amount of time;
• and
• a code segment executed by the host computer for periodically querying the database to locate all flagged records and pushing flight status change notification information to each passenger or agent who has requested notification information on each flight corresponding to a record that has been flagged.
