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 , 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.
