Japan Airlines is giving away 50,000 free round-trip flights this summer, but winners don't get to pick their final destination.

It's an effort by the airline to get travelers to discover less-visited cities. Flights depart from and return to Tokyo (Haneda Airport) and Osaka (Itami Airport and Kansai International Airport) only.

The travel period is July 1 through Sept. 30. The summer of 2020 is a great time to visit Japan: the Olympics are being held in Tokyo.

To have your application considered, provide the details of your flight and become a member of the airline's mileage program.

Within three days of your application, the airline will tell you to which destination you'll travel. Apply on the airline's website.
