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.
By public transit
Between airport and city
Bus and taxi are the options, there's no rail or metro link.
- Aircoach (the big blue bus) runs to city centre and several of Dublin's major hotels, which are mostly south-side. Buses run from T1 then T2 every 15 min, taking 30 min, fare is €7 single or €12 return. Aircoach also run to other cities, including Cork and Belfast. Taxi drivers routinely try to pick up passengers waiting at the Aircoach stop: they're forbidden to do so, but offer a similar rate and get many takers, so they persist.
- AirLink Buses 747 and 757, operated by Dublin Bus, run daily 05:00-00:30 every 10 min or so daytime for route 747 and about every 30 min for route 757. They take 30 min from T1 via T2 and the tunnel into dockland; then they hit the downtown traffic and make slow progress. The 747 goes via Central Bus Station (Busáras), Connolly Railway Station, Gardiner St, O’Connell St, College Green & Temple Bar, Christ Church Cathedral, High St, Ushers Quay and Heuston Railway Station. The 757 runs further south via Custom House Quay, O’Connell Bridge, Hawkins St & Temple Bar, Westland Row, Merrion Square, St Stephen’s Green, Camden and Harcourt St. The fare (cash only) is €7 single, €12 return or free if you buy a Leap Visitor Card in the terminal before boarding.
- Local buses are much slower — allow an hour — but cheaper (typically €3.30) and may be more convenient for the suburbs. The two routes are:
- — Bus 16 via Drumcondra railway station, O'Connell St, Georges St and out to the southern suburbs of Rathmines and Ballanteer / Kingstown.
- — Bus 41 via Drumcondra railway station and O'Connell St, passing near Busáras, to Lower Abbey St. Northbound it runs out to Swords.
- The stops for the local buses are at Terminal 1 through the car park opposite Arrivals exit and then to the right. Pay with coins only, the ticket machines give change but bus drivers don't. Luggage space is limited on the local buses, and it is not unknown for drivers to turn away travellers with packs that cannot be stored.
- A taxi to the city centre should cost around €20-30, so it will match the bus if you are in a group of three or more. Taxis are legally obliged to provide an electronic receipt detailing the fare, distance and other pertinent details. Make sure to ask for a receipt as otherwise they often don't provide one.
Many Bus Eireann routes between Dublin and other Irish cities run via the airport, see individual cities' "Get in". Within County Dublin:
- — Bus 101 runs every 20 min to Balrothery, Balbriggan and Drogheda. This bus runs from Dublin Talbot St via Drumcondra but is not available for journeys just between city, airport and Swords.
- — Bus 102 runs from the airport every 30 min to Swords, Malahide, Portmarnock and Sutton near Howth.
- — Drumcondra (Bus 16 & 41) has trains from Connolly towards Maynooth.
- — Aircoach Bus 700 runs to Leopoldstown & Sandyford, 702 to Bray & Greystones, and 703 to Dún Laoghaire, Dalkey & Killiney.
All the main car hire companies have kiosks in Arrivals. There's much better choice here than in city centre, but book ahead for the best deals. The airport has car parking short-term on-site, long-term off-site, and "meet & greet" services.
There are three Lounges run by Dublin Airport. One in Terminal 1, one in Terminal 2 and one after U.S. Border Preclearance. Lounge access can be pre-booked online for €25 (lounges in Terminal 1 & 2) or €35 (Lounge past U.S. Border Preclearance) which represents a €4 discount from the walkup rate.
Eat and drink
The currency kiosks are run by ICE with a 10% buy/sell rate, decent value.
There's the Radisson Blu and Maldron hotels at the airport and a few more at the M1/M50 junction just south and in Swords to the north.
