Is one way ticket expensive?

Round-trip tickets are usually cheaper than one-ways, sometimes significantly so. NerdWallet compared fares across multiple international routes and found that, typically, buying two one-way tickets costs 20% more than a single roundtrip.



In 2026, the price of a one-way ticket depends heavily on whether the route is domestic or international. For domestic U.S. flights, most carriers have moved to a "segment-based" pricing model where two one-way tickets usually cost the exact same as a round-trip fare. However, for international travel, one-way tickets can still be significantly more expensive—sometimes even costing more than a full return ticket. This is because airlines use one-way fares as a premium for the "flexibility" often required by business travelers or those on long-term visas. For budget-conscious travelers in 2026, it is often cheaper to book a "hidden city" flight or a "throwaway" return leg rather than a standalone international one-way. That said, low-cost carriers like Norse Atlantic or French bee have made international one-way pricing much more competitive than it was a decade ago.
