The One of the most common pieces of advice is to set your browser to private or incognito mode before searching for tickets. If you repeatedly search the same route in your browser’s regular mode, you’ll likely see the price go up. It’s also a good idea to check multiple search engines and compare their prices; Skyscanner, Google Flights, Kayak, Momondo, and CheapOair are good places to start. If your travel dates aren’t set in stone, use the “flexible dates” feature to compare prices for a week’s worth of flights. Many search engines don’t include budget carriers, though, so if they’re not showing up, check their websites separately. Low-cost airlines to keep in mind include JetBlue, Frontier, and Spirit in the U.S.; Ryanair, EasyJet, and Wizz Air in Europe; and Air Asia, Tiger Air, and Spice Jet in Asia. For long-haul trips, check before you book to see if it’s cheaper to buy separate legs of the trip individually (but do be aware that you’re unlikely to receive assistance from the airline in the event of a missed connection). Similarly, always check to see if buying two one-way tickets is cheaper than a round trip. Finally, if you’re not pressed to book right away, set up a fare alert on Skyscanner or Airfare Watchdog to keep you up-to-date on the price of flights you’re interested in.
