A situation occurs when a requested reservation on a portion of a journey by air cannot be immediately confirmed due to limited availability. For instance, a traveler might secure a confirmed seat from New York to London but find the connecting flight from London to Rome placed in a queue awaiting an available seat. This often happens when high demand outstrips the supply of seats, especially during peak travel seasons or on popular routes.
Managing these situations effectively is crucial for both airlines and passengers. Airlines utilize waitlists to maximize capacity and minimize empty seats, improving operational efficiency and revenue. For travelers, understanding the implications and procedures associated with these scenarios can help alleviate stress and increase the likelihood of securing a desired seat. Historically, managing these situations relied on manual processes, but advancements in technology have automated much of the process, allowing airlines to manage waitlists more efficiently and provide passengers with more timely updates.
