Simple Ways to Save at KAYAK

KAYAK is a powerful search engine for travel, and the best way to save is to use its built-in tools. You don't need to be an expert to start saving money right away.

  • Use the Price Alerts: This is the easiest win. When you search for a flight or hotel, turn on the price alert. KAYAK will email you when the price changes, so you can book when it drops.
  • Check the "Price Forecast": On flight searches, look for the "Price Forecast" badge. If it says "Buy Now," KAYAK predicts prices will rise. If it says "Wait," prices might drop soon.
  • Search for "Anywhere": If your travel dates are flexible but your destination isn't, use the "Explore" tool. Enter your budget and dates, and KAYAK will show you a map of all the places you can afford to go.
  • Always Compare: KAYAK searches hundreds of sites. Always look at the "Other Sites" tab to make sure you're seeing the best deal from all available options.
