In 2026, the cost of flying standby has shifted toward a "free-for-some, fee-for-others" model. For many major airlines like United, Delta, and American, "Same-Day Standby" is now a complimentary service for all passengers, allowing you to list for an earlier flight on your original day of travel for no charge. However, you only get the seat if one is available after all confirmed passengers have boarded. If you want a confirmed change (guaranteeing you a seat on a different flight), you will typically pay a fee ranging from $50 to $75, unless you are a high-tier elite status member. For airline employees and their "buddy pass" holders, standby is nearly free, with the user only paying the applicable taxes and a small administrative fee. It is important to distinguish between "voluntary" standby and "involuntary" standby (caused by a cancelled flight); in the latter case, the airline will move you to the next available flight for free. While the days of $25 "hidden" standby fees are mostly gone for casual travelers, the real "cost" is now your time and the uncertainty of whether you will actually make it onto the plane at the gate.
