The duration of a flight stop—commonly referred to as a layover—can vary wildly from a "tight" 30 minutes to a marathon 23 hours. For domestic connections, a standard layover usually lasts between 1 and 2 hours, providing just enough time to traverse the terminal. International stops are typically longer, often 2 to 4 hours, to account for potential delays, additional security screenings, or passport control. Airlines set a "Minimum Connection Time" (MCT) for every airport, which is the shortest window they believe a passenger can realistically make their next flight; if your stop is shorter than the MCT, the airline won't even sell you the ticket. If a stop exceeds 24 hours, it is technically classified as a "stopover," and many travelers intentionally book these to explore a "bonus" city for a day or two. In 2026, many major hubs like Singapore Changi or Doha Hamad International offer transit hotels and even "free city tours" for passengers with stops longer than 6 hours, turning a logistical necessity into a mini-vacation. Conversely, a "technical stop" for refueling usually only lasts 45 to 60 minutes, often without passengers ever leaving the aircraft.
