An "Open Jaw" flight gets its name from the V-shape it creates on a map, resembling a gaping mouth or "jaw." In 2026, this refers to a high-value multi-city itinerary where you fly from Point A to Point B, and then return to Point A from a different city, Point C. For example: flying New York to London, then taking a train to Paris, and finally flying Paris back to New York. The "gap" between London and Paris is the "open" part of the jaw. This is a premier strategy for travelers who want to see more of a region without wasting a whole day of their vacation backtracking to their arrival city. Open-jaw tickets are often priced similarly to standard round-trips, making them a high-value alternative for exploring Europe or Asia efficiently. By eliminating the "return loop" to the first city, you maximize your exploration time and often save significant "last-mile" transportation costs on your journey home.
