To search multiple airlines at once, there’s Google Flights, which has simple calendars that allow users to easily see if they can save by flying a day or two earlier or later. The tool offers tips to that end. During a recent flight search for New York to Cancún, a message appeared saying that if I adjusted the travel dates by a few days, I could save $246. While the site has international and domestic flight information for nearly every airline, you won’t find Southwest there, so be sure to look at the airline’s own fare calendar on its website.
To keep abreast of private sales and low fares (as well as hotel deals), you can search or sign up for alerts on Airfarewatchdog.com. Email alerts include low fares for a particular route that interests you, or all of the affordable round-trip flights departing from your local airport.
Because prices are constantly fluctuating, keep checking airline websites and Google Flights to see the latest fares. The ticket price you see before lunch may be different a couple of hours later.
Even after you buy a ticket, you still have a chance to save. If you go to My.yapta.com/airline-refunds, you can sign up to receive free notifications if your ticket price drops.
