Best times to search for fares
February 12, 2007
according to Travel+Leisure, Feb 2007:
Act at the right time. To increase your chance of getting a good price on your next flight, keep in mind that carriers must release new airfares to a central clearinghouse (called the Airline Tariff Publishing Company) at certain hours; on weekdays, the best times to look for new fares are just after 2 p.m., 4:30 p.m., and midnight. T+L tip: Tickets that were reserved but never paid for usually appear after midnight, so the selection is especially rich then. On weekends, fares are updated just once a day, around 5 p.m.
