Why the two directions differ

New York to London is usually scheduled about an hour shorter than London to New York. Over the North Atlantic, as across most mid-latitudes, winds at cruising height blow mainly from west to east, sometimes at well over 150 km/h in the jet stream. Our flight-time estimate integrates a latitude-dependent westerly wind along the great circle, calibrated against 109 published scheduled durations on 55 routes; across them it is typically within 9 minutes.

What we don’t cover

Airline schedules, which carriers fly a route, fares and live flight status come from proprietary systems, so we don’t show them and we don’t guess. What you get here is geometry, time zones and a transparent estimate — the parts that can be computed from open data and checked.
