The airport layover guide helps you assess if your connection time is sufficient and what to do during short, medium, and long layovers at major international airports.
Making the Most of a Layover
A layover is only stressful if it's too short or you're unprepared. Connections under 60 minutes at a large airport with an international arrivals component are genuinely risky. Airlines won't hold the plane, and rebooking waits can be 4-8 hours.
Minimum connection times (MCTs)
Airlines publish Minimum Connection Times — the absolute minimum the airline considers feasible. These are not safe in practice; they assume everything goes perfectly. Add 30-45 minutes buffer. For international arrivals with customs and immigration, 90 minutes is a true minimum at most airports; 2 hours is safer.
Long layover city visits
Singapore (Changi), Dubai, Seoul Incheon, and Amsterdam Schiphol offer free or discounted city tours for transit passengers with 6+ hour layovers. Check the airport website. Always verify transit visa requirements before exiting — US passport holders can transit most countries without a visa, but rules vary significantly by nationality and destination country.
Frequently Asked Questions
How long do I need for a domestic connection?
At most US airports, 45-60 minutes is the practical minimum for domestic-to-domestic connections if you're pre-screened (TSA PreCheck, same terminal). 60-75 minutes is safer. For international arrivals connecting to domestic, add 60-90 minutes for customs.
Is a 1-hour international layover enough?
Usually not. International connections require clearing immigration and customs (30-90 minutes), possibly re-checking bags, and finding the next gate. Most experienced travelers recommend 2-3 hours minimum for international connections.
What happens if I miss my connection?
If your flights are on the same booking/ticket, the airline must rebook you at no charge. If you booked separately, you bear the cost. Travel insurance can cover this. Airlines may also provide hotel vouchers for long delays caused by the airline.
Can I leave the airport during a layover?
It depends on whether you need a transit visa and how much time you have. US passport holders can enter most countries without a transit visa. Allow at least 4-6 hours for a city visit — factor in immigration, customs, and getting back in time.
