A method, computer program, and system for automatically pushing flight status information to passengers and/or their agents whenever an airline flight is delayed, cancelled, or otherwise subject to a status change. The invention is implemented with a computer program that instructs a host computer operated by a global airline distribution provider. The computer program includes: a code segment 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 for receiving and storing in the database any updated times of departure or arrival for the flights; a code segment 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 for flagging records in the database corresponding 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 for periodically querying all flagged records and pushing notification information to at least one passenger or an agent of the passenger on each flight corresponding to a record that has been flagged.
