Do you have to go through airport security during a layover?

For domestic-to-domestic layovers, you normally won't have to go through security again during your layover. However, for all international layovers, you will normally have to go through security again, but this will depend on individual airport policy.



Whether you must clear security during a layover depends entirely on your arrival and departure terminals and the specific laws of the country you are transiting through. For domestic-to-domestic layovers in the United States, you typically stay "airside" and do not need to pass through security again. However, if you are arriving on an international flight to the U.S., you are legally required to clear Customs and Border Protection (CBP) and then re-pass through TSA security to reach your connecting gate, even if your bags were checked through to the final destination. In many international hubs like London Heathrow or Dubai, passengers transferring between certain terminals may also be required to go through a secondary security screening. If you decide to leave the airport during a long layover to see the city, you will absolutely have to clear security upon your return. The general rule is: if your transit requires you to exit the "secure" zone or enter a different country's jurisdiction, a security re-screening is almost always mandatory to ensure the safety of the next flight segment.

It's not against the law. But it is a violation of the contract of carriage you entered into when you bought your ticket. Many people do this.

The main difference between a stopover and layover is length of time. Stopover rules vary by airline, but are essentially longer layovers — at least 24 hours in length. Layovers, meanwhile, are connections less than a day in length depending on if you're flying domestically or internationally.

Here's how the process usually goes: When you arrive at the layover destination, you'll have to pick up your checked bag inside the airport at a designated area. You won't be able to miss it, since the airline staff won't let you wander around the airport without rechecking your luggage first.

The recommended layover time for international flights is generally longer, as you will have to go through customs and immigration before boarding your next flight.
