Here’s how it works
A bunch of airlines have a page on their websites where you can shop just for stopover deals. At this point you’re probably wondering what’s in it for them: Assuming you have the time to spare, stopovers are in both your best interests and the airline’s. It allows them to bring tourists into major hubs where they themselves are based — like Emirates using stopover packages to entice people to Dubai, or Turkish Airlines’ stopovers in Istanbul. The Star Alliance airlines’ Round the World program lets you put as many as 15 stopovers on one ticket if you want. The point is to encourage you to explore and spend money shopping and dining, instead of just sleeping on the floor of the airport for a few hours without ever going outside.
