The status “closed” in relation to an airline flight signifies that the check-in process for that specific departure has concluded. No further passengers can be accommodated, even those holding confirmed reservations. This typically occurs a specific timeframe before the scheduled departure to allow for final preparations, such as baggage handling, passenger counts, and weight balancing. For instance, a domestic flight might close 30 minutes prior to departure, while international flights often have longer closure times.
Timely closure facilitates operational efficiency and ensures on-time departures. It allows airlines to finalize essential pre-flight procedures without interruption and maintains predictable scheduling. Historically, flight closure times were less standardized, leading to potential delays and confusion. The implementation of stricter closure windows contributes significantly to the improved punctuality observed in modern air travel. This standardization also benefits passengers by providing clear expectations and reducing last-minute boarding rushes.
