How to Save by Booking Two One-way Tickets Instead of a Round-trip

Booking two one-way tickets instead of a round-trip flight can get you greater savings at times, but it can be tough to know when to make this move.

That's why Kayak has released its first Flight Hacker Guide, highlighting 10 international cities and 10 domestic cities where travelers can save as much as 16 percent on a ticket by booking two one-way fares.

The cities highlighted are those that provide the biggest savings for bookings, based on searches conducted on Kayak's U.S. site from June 15, 2017 through June 14, 2018 for travel during those dates.

The search platform also took a look at median fares each month in these cities to let you know when you can expect to book the best deal.
