🔁 Layover & Connection Calculator
Enter your arrival and next-departure times to see how long the layover is — and whether it clears a typical minimum connection time.
Layover
1 h 45 m
Comfortable — about 1 h 0 m above the typical 45-minute minimum.
Minimum connection times vary a lot by airport, terminal and whether you re-clear security or immigration; the figures here (domestic ~45 min, international ~90 min) are rough safety floors, not guarantees. On a single ticket the airline protects you if a delay makes you miss a legal connection; on separate tickets you don't have that protection, so leave much more time. 🔒 In your browser.
How the layover & connection calculator works
The layover is simply the gap between when your first flight arrives and your next one departs. The tool works out that gap (handling connections that spill past midnight) and compares it to a typical minimum connection time for the type of connection — domestic-to-domestic, international, or a mix where you re-clear security and immigration and may re-check bags.
Minimum connection times are set per airport and can be much longer at big hubs or when changing terminals; these defaults are rough safety floors. Crucially, on a single ticket the airline must rebook you if a delay makes you miss a legal connection — on separate tickets it won't, so leave a generous buffer when self-connecting.
Frequently asked questions
How much layover time do I need?
As a rough floor, about 45 minutes for a domestic-to-domestic connection and 90 minutes or more for international connections where you re-clear security or immigration — but big hubs and terminal changes need more. When in doubt, give yourself extra.
What is a minimum connection time?
The shortest gap an airport/airline considers a valid connection, accounting for the walk between gates, security and (for international) immigration and bag transfer. Airlines won't sell a single-ticket connection shorter than it.
Is a 1-hour layover enough?
Often yes for a domestic connection at a familiar airport, but it can be tight internationally or when changing terminals. If your flights are on one ticket you're protected against a missed connection; on separate tickets, an hour is risky.
What happens if I miss a connection?
On a single ticket the airline rebooks you on the next available flight at no charge (and covers care for long delays under some rules). On separate tickets you bear the cost of a new flight — the reason to leave more time when self-connecting.
Does the calculator handle overnight layovers?
Yes — tick "next day" when the departure is after midnight relative to the arrival, and it adds the 24 hours so the layover comes out right.
