Generally, yes—booking a round-trip ticket to the same airport is usually cheaper than booking "Open-Jaw" flights (flying into one city and out of another) or two separate one-way tickets. In 2026, airline pricing algorithms still favor the predictability of round-trip bookings, often offering a "bundle" discount that can be 10% to 30% lower than the sum of two one-way fares. However, there are exceptions: low-cost carriers (like Southwest or Ryanair) often price their flights as simple one-way segments, meaning there is no financial penalty for flying into a different city. For international travel, "Multi-City" bookings can occasionally be comparable in price if the cities are major hubs for the same airline alliance. While it is usually cheaper to fly in and out of the same place, you should weigh the savings against the cost and time of traveling back to your original city, which may "eat up" the initial flight savings.
