Wow, 35,000 flights per year between LON and DUB!
Worth pointing out that the
www.flightontime.info data on Key Routes analyses
movements at London Airports so both departures to Dublin and arrivals from Dublin are included in the 35,000 - equating to rougly 17,500 flights in each direction on the route.
Still nearly 50 flights per day though...
LON Airports to Milan Airports (LIN/MXP/BGY) in terms of scheduled flight movements comes 11th on the
Key Routes List.
