A layover is a scheduled stop between the departure and final destination of a flight itinerary. Once you land at the layover airport, you disembark the first plane and typically check the departure monitors to find the gate for your next "connecting" flight. On a single ticket, your checked baggage is usually transferred automatically to the next aircraft, though you may need to clear security or immigration if you are transitioning from an international to a domestic flight. During the wait, which can range from 30 minutes to nearly 24 hours, you are free to use airport amenities like lounges, restaurants, and shops. In 2026, many major hubs like Singapore Changi or Doha Hamad have integrated "transit hotels" and nap zones for long layovers. If the layover is significantly long and you have the proper visa, you may even be able to leave the airport for a few hours to explore the local city before returning for your second leg.
