Distance is the great-circle distance between London Heathrow and Dublin. Time is that distance at about 830 km/h cruise, adjusted for the prevailing jet stream, plus roughly 35 minutes for taxi, climb and descent. It is a typical scheduled-time estimate, not a timetable: airlines publish their own, and daily winds, routing and air traffic can move a long flight by half an hour or more. Reviewed October 2026.
