Why Have a Layover Under 24 Hours
A layover under 24 hours is mainly to connect flights that don't have a direct route, allowing passengers to switch planes efficiently.
It's often said that a layover under 24 hours automatically lets you travel without a visa — in fact, transit and entry rules depend on your passport, airport, route, and whether you stay in the secure transit area.
Layovers help airlines offer more destinations by linking flights, making travel possible even when there isn't a direct flight, and sometimes giving travelers a short break between long trips.
It's like when you need to stop at a friend's house briefly before going to a party; you pause your trip just long enough to get to the next place.
When comparing flight options, the length and setup of a layover can matter as much as the total travel time, especially if a delay could affect your next flight. Knowing whether your flights are booked together also helps you understand what support you may have if plans change.
Imagine a flight arrives at 11:00 and the next one leaves at 13:00. If walking to another terminal takes 25 minutes, passport checks and security take 40 minutes, and boarding closes 30 minutes before departure, only 25 minutes remain for unexpected delays; a 20-minute delay on the first flight could leave too little time.
Connection time needs a buffer
A short gap between flights can be stressful when you need to change terminals, go through security, collect bags, or pass border checks.
One booking can make changes easier
When connecting flights are sold together on one ticket, the airline can often help rebook you if an earlier flight delay makes you miss the next one.
Leaving the airport has rules
Whether you can go outside during a layover may depend on your passport, visa requirements, checked baggage, and the airport's security process.
