Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation.
