Save Money on Airline Tickets With These Websites

1. Kayak

Kayak searches hundreds of websites at one time, turning up the web's best flight deals.

You can also set fare alerts for flights. Choose preferred travel dates to destinations of your choice. Kayak fare alerts can be scheduled as daily, weekly or monthly emails.

2. Yapta

Yapta is an online tool that helps travelers keep a close eye on airline prices, before and after ticket purchases.

Flyers can use Yapta — now powered by Kayak — to search for the cheapest flights in the upcoming months.

Yapta's super power lies in its ability to track fare changes after tickets have been purchased. If prices drop, Yapta users can claim an airline refund for the difference directly on the platform.

Most travelers aren't aware of airline refund policies. Some airlines offer a refund with any price drop, while others offer a refund when the price drops below a specified amount.

3. Student Universe

Student travelers can buy discounted flights to destinations all over the world with StudentUniverse.com .

4. Skyscanner

Skyscanner is a flight comparison platform that lets travelers display the lowest airfare available in a month or year on a graph, so users can quickly pick the cheapest dates to travel.

One search on Sky Scanner compares offers from 600+ airlines, covering more than 67,000 routes worldwide. Like Kayak, Sky Scanner directs customers to official booking websites without fees.

If you haven't decided where to spend your vacation days, use Sky Scanner's "Search Everywhere" option to see where the cheapest flights are leaving from the airports nearest you.

Cut additional costs by searching for "indirect" routes or by using the "flexible" search tool — to mix and match airlines.

6. Airfare Watchdog
