In 2019, 32.9 million passengers passed through the airport, making it the airport’s busiest year on record. It is the 12th busiest airport in Europe, and is by far the busiest of Ireland’s airports by total passenger traffic. Due to the strong ties between Ireland and the UK, the London-Dublin route (with flights to all London airports) is among the busiest air routes originating in the EU.
Dublin Airport has an extensive short and medium haul network, and is the base for Aer Lingus, Aer Lingus Regional, and Ryanair. Terminal 2 can accommodate wide-bodied jets and is used by Aer Lingus (& Regional), American Airlines, Delta, Emirates, Norwegian and United. All the others use the older Terminal 1, some 300 m north with a walkway between. Together they offer direct flights to most major cities in UK (serving all London airports, but most frequently Heathrow) and Europe (including Keflavik Airport, Moscow and Istanbul Airport). North America is well-served, with flights to New York JFK Airport, Newark Liberty Airport, Boston Logan Airport, Chicago O’Hare, Orlando International Airport, Philadelphia International Airport, San Francisco Airport, Seattle Tacoma Airport and Washington Dulles Airport (with pre-clearance of US customs & immigration before flying) and Toronto. Middle East flights include Dubai Airport, Doha Hamad Airport and Abu Dhabi. Domestic flights are to Kerry and Donegal; there are no flights to Belfast, Shannon or Cork.
