What is a standby list and how does Delta Airlines utilize it for their flight operations?

A standby list is a list of passengers who do not have a confirmed seat on a flight but are hoping to get on if there are available seats. Delta Airlines uses a standby list to manage last-minute changes, such as missed connections or overbooked flights. Passengers can request to be on the standby list at the airport or through the airline's app, and Delta will prioritize passengers based on factors like frequent flyer status and fare class. If there are open seats before the flight departs, Delta will assign them to passengers on the standby list in order of priority.
