Layover Time Planner
Plan connecting flights with local arrival and departure times, time zone changes, and layover duration estimates. Uses browser IANA time zone data and open airport data — no server calls.
Connection planning
Estimate your layover
Understand your connection at a glance.
Enter your departure and arrival details for each flight leg. The planner shows the local time at each stop, calculates layover duration, and flags overnight connections or time zone shifts that might affect rest, meal planning, or airport services.
Layover durations are planning estimates only. Actual connection time depends on airline scheduling, air traffic control, gate assignments, security queues, and airport layout. Always follow your airline's minimum connection time recommendations and airport signage.
The optional third leg adds the onward departure time so you can see the full journey including total travel time across multiple time zones.
Open airport data and browser time zones.
Airport search uses OurAirports airports.csv — public-domain airport data maintained by the community. Time zone handling uses the browser's built-in Intl.DateTimeFormat API with IANA time zone identifiers. No external API calls are needed once the page loads. Last reviewed: May 15, 2026.
