Two multi-city itineraries you definitely want to know.

If you thought the only way to reserve a flight was by booking a one-way or round-trip ticket, let us introduce you to the slightly more complex (but incredibly rewarding) world of multi-city itineraries.

Instead of flying from city A to city B (a standard one-way flight), or from A to B and back to B (your typical round-trip route), travelers can instead plan a round robin itinerary, or an open jaw itinerary.

Both let you see more than one destination on your trip — and can, on occasion, yield serious savings.

Round Robin Trips

The simpler of the two, a round robin ticket is just another term for a standard multi-city booking, which can often be done using a flight search tool like Kayak or Skyscanner.

Multi-city bookings like this can be a great way to take advantage of a long stopover — or visit both families during the holidays.

But round robin trips can also be used to book complicated multi-stop itineraries, like those around-the-world journeys that take advantage of multiple flight deals in one seamless booking. (Last September, the Airfare Spot created a round robin-style trip around the world with stops in five cities for only $1,161.)

Open Jaw Trips

Travelers who book an open jaw trip fly from city A to city B, and then fly from city C back to city A. Logistically, a trip like this requires more work on the traveler’s part. You’ll be responsible for getting yourself to the next city, whether you want to cycle, hike, kayak, or take a cheap regional flight.

According to Scott’s Cheap Flights, for example, travelers can currently find ultra-cheap 2-for-1 flights to Southeast Asia using an open jaw fare.

You can book a $380 flight from either Los Angeles or New York City to Singapore, for example, and return from Bangkok, Shanghai, Kuala Lumpur, or Manila.

Cheap regional flights may cost as little as $33 one-way, making it easy (and incredibly affordable) to see two cities in Asia for the price of one. Just make sure you can get between, say, Singapore and Bangkok in time for your flight home — especially if you're getting there in an unconventional way.
