In the strict sense, traditional "open-ended" tickets have largely disappeared from direct consumer websites in 2026, but they still exist through specialized travel agents or as fully flexible fares. Most airlines now require a specific date to generate a booking reference and calculate taxes. However, you can achieve the same result by purchasing a "Flexible" or "Freedom" fare, which allows for unlimited date changes without penalty, sometimes even up to an hour before departure. Another common strategy in 2026 is to book a one-way ticket if you are unsure of your return, or to use "Round-the-World" (RTW) passes offered by alliances like Star Alliance, which allow for date modifications as you travel. While more expensive upfront, these flexible options provide the peace of mind needed for open-ended adventures without the risk of high change fees.
