Shannon had 2,250 flights to and from the United States in the twelve months to June 2026, about three departures a day in each direction spread over 4 US routes, the busiest being New York (JFK) with 838. EUROCONTROL publishes no punctuality series for the airport, so its own figures cannot be quoted here. Ireland publishes no route-level punctuality, so the US routes below are described by frequency and carrier rather than by delay.
By transatlantic volume it is 23rd of the 45 European airports with a page here; London Heathrow leads with 81,419 flights. Punctuality and volume do not move together: a hub's transatlantic bank is scheduled around its own connecting flights, and the arrivals that feed it are where the delay comes in.
