There are many reasons for being placed on the standby list, but here are some of the most common: You or someone you know works for an airline. It could be that you are using airline benefits, including buddy passes. You don't want to take your original flight for voluntary reasons.

In 2026, getting on a standby list typically happens through the airline's mobile app or via a gate agent on the day of travel. There are two main types of standby: Same-Day Standby, where a passenger with a confirmed ticket wants to catch an earlier or later flight, and Involuntary Standby, for those whose original flights were cancelled or who missed a connection. Most major airlines like Delta, United, and American allow "Elite Status" members to add themselves to the standby list for free via the app starting 24 hours before departure. For everyone else, there is often a fee (usually $50–$75) that is only charged if you actually get a seat. Another way is through "Buddy Passes" given to airline employees, which place travelers at the bottom of the priority list. In all cases, the list is prioritized by ticket class and frequent flyer status. Passengers must remain near the gate, as names are often called just 10–15 minutes before the door closes.
