Look for deals on domestic flights between Tuesday at 3 p.m. and Thursday night, when fare sales typically occur, says Rick Seaney, who heads the travel website FareCompare.com, based in Dallas. Experts say many travel websites also provide alerts, which broadcast special deals, often within a short window of opportunity. Typically, such alerts are good deals if, on a US domestic flight, they cost (with taxes and fees) less than $150 for a flight lasting less than 90 minutes; $200 or less for a flight of two to three hours; and $300 or less for flights longer than three hours, Mr. Seaney says.
