Overview
Dublin Airport (IATA: DUB) sits on the former Collinstown Aerodrome, just 10 km north of Dublin city centre. Operated by the DAA, it is the 12th busiest airport in Europe and the busiest on the island of Ireland, processing more than 36 million travellers in 2025. The airport serves as the primary hub for Aer Lingus and a major base for Ryanair, offering an extensive short‑haul network across Europe and a growing long‑haul portfolio to North America, the Middle East and Asia.
Two adjoining passenger terminals – Terminal 1 (opened 1972) and the sleek Terminal 2 (opened 2010) – are linked by a covered walkway, allowing passengers to move freely between them after security. A unique feature is the United States border pre‑clearance facility, one of only two in Europe, which lets US‑bound passengers complete immigration and customs in Dublin, arriving in the United States as domestic travellers.
History
The site began as a wartime aerodrome in 1917, used by the British Royal Flying Corps. After the Irish War of Independence the airfield fell into disrepair, but the 1930s saw a civilian revival. The inaugural commercial flight left for Liverpool on 19 January 1940, and the original Art Deco terminal – designed by Desmond FitzGerald – opened in early 1941, later earning the RIAI Triennial Gold Medal.
Post‑World War II expansion was rapid. A new North Terminal opened in 1959, and the first purpose‑built passenger building (now Terminal 1) was inaugurated in June 1972 to accommodate Boeing 747s. The airport survived a tragic bombing in 1975 and continued to grow through the 1980s and 1990s, adding Pier C with air bridges and, in 2007, Pier D for low‑fare quick‑turn‑around stands.
The 21st‑century saw the opening of Terminal 2, a €600 million, 75 000 m² facility that houses Aer Lingus, US carriers and Emirates, and the relocation of US pre‑clearance from Terminal 1. A new parallel runway (10L/28R) opened in August 2022, raising the airport’s capacity to around 30 million passengers annually, with plans for further expansion.
What to See & Do
Even as a transit hub, Dublin Airport offers several experiences that feel distinctly Irish:
- Art and Architecture – Terminal 2’s centerpiece is The Spirit of Place by Isabel Nolan, a striking sculpture that greets arriving passengers. The historic 1940 terminal, still listed, can be glimpsed from the link corridor.
- Shopping – The Loop, the post‑security retail zone, hosts duty‑free outlets, Irish craft stores and a Click‑&‑Collect service that lets you shop online and pick up purchases on your return.
- Food & Drink – From quick‑service cafés to sit‑down restaurants, the terminals serve everything from Irish coffee to international cuisine. A local oddity is Nect‑Air honey, harvested from hives on airport land and sold in the Marqette restaurant.
- Live Music – Seasonal performances feature school choirs, local bands and the Airport Police & Fire Service Band, adding a community feel to the bustling halls.
- Lounges – The 51st & Green lounge, located after US pre‑clearance, offers a quiet space with runway views, complimentary food and drinks for a fee or for business‑class passengers.
- Family Facilities – A dedicated family room in Terminal 1 provides a high‑chair, bottle warmer and toys, making travel with young children smoother.
- Plane Spotting – The south end of runway 10/28 offers a safe, walkable viewpoint for aviation enthusiasts.
- Nearby Coastal Walk – A short drive north brings you to the sandy stretch of Portmarnock Beach and the Velvet Strand, popular for a quick walk or a coffee break before a flight. The suburb of Baldoyle lies just east of the airport and offers additional cafés and a seaside promenade.
Practical Information
Getting Here and Away
- Road – The airport sits adjacent to the M1 and M50 motorways. Short‑term car parks cost €3 for the first hour and €4.50 per additional hour (max €40 per day). Long‑term car parks and several on‑site hotels provide shuttle services. [Parking fee rates should be verified for any recent changes].
- Buses – Over 60 bus routes serve the airport. The Aircoach 700 runs 24 hours, departing every 15 minutes to the city centre. Dublin Express and local Dublin Bus routes (e.g., 41, 16) also connect to key districts. All bus stops are a short walk from the arrivals level of each terminal.
- Taxis – Metered taxis rank outside both terminals; a typical city‑centre fare is €25‑30. Ride‑hailing apps such as Free Now can be used, but vehicles must pick up at the official taxi rank.
- Car Hire – Major international and Irish rental companies have desks in both terminals. In Terminal 2 the desks are in the multi‑storey car park; in Terminal 1 they are in the arrivals hall.
- Rail – No direct rail link exists yet, but a MetroLink line is planned for completion around 2035, promising a fast underground connection to the city.

Security & Customs
US‑bound passengers clear immigration and customs at the pre‑clearance desks before boarding; this eliminates queues on arrival in the United States. Passengers travelling to other destinations follow the standard Irish customs process, with green (nothing to declare) and red (goods to declare) channels.
Recent Developments & Future Plans
- New Runway – The 10L/28R runway opened in August 2022, enabling simultaneous use of two main runways and supporting future long‑haul growth.
- Air Traffic Control Tower – A new 84‑metre tower opened in June 2022, the tallest inhabited structure in Ireland, ready for the expanded runway operations.
- Expansion Projects – Plans include two additional passenger piers, an air‑side tunnel linking remote stands, and a possible third terminal to the west of the current campus (still under negotiation).
- Drone Incidents – Early 2023 saw several drone sightings that caused temporary flight disruptions; the DAA is working with Gardaí on a counter‑drone system.
Practical Tips for Travelers
When departing for the United States, allow at least three hours for check‑in, security and pre‑clearance; Aer Lingus recommends the same window year‑round. For European flights, a two‑hour window is usually sufficient. Fast‑Track security can be purchased online and used at dedicated lanes.
Dublin Airport is more than a transit point; it is a showcase of modern Irish hospitality, art and efficiency. Whether you have a quick layover or are beginning a longer Irish itinerary, the airport’s facilities, transport links and unique US pre‑clearance make the first step of your journey smooth and memorable.
