How Many Airports in Ireland? A Thorough Guide to the Island’s Air Links
If you’ve ever found yourself asking, “How many airports in Ireland are there?”, you’re not alone. The answer isn’t as simple as a single number, because it depends on how you define an airport, what counts as a regular passenger service, and whether you include the entire island or only the Republic of Ireland. This guide unpacks the question in a clear, reader‑friendly way, with practical details to help you plan travel, understand aviation on the island, and navigate the sometimes confusing landscape of Irish air travel.
How to count: airports, airfields, and what counts as a flight hub
Before tallying, it’s useful to distinguish between different kinds of air facilities. A straightforward way to count is to separate airports with regular passenger services from those that are primarily used for general aviation (private pilots, flight schools, charitable organisations) or for cargo, military, or para‑statical purposes. Some airfields function primarily as relievers or secondary hubs, while others handle international or domestic routes with scheduled services. The island of Ireland has examples of each, which is why the number can vary depending on what you include.
Key distinctions include:
- Public passenger airports: facilities with scheduled flights for the general public. These are the ones most travellers think of when they ask, “How many airports in Ireland are there that I can use for a trip?”
- Regional and domestic hubs: smaller airports that offer limited routes, often to Dublin or other UK and European destinations, sometimes seasonal.
- General aviation airfields: airstrips used for private planes, flight training, or recreational flying; typically not suitable for routine passenger services.
With those distinctions in mind, the commonly cited figure refers to the number of public passenger airports on the island of Ireland. This figure can be expanded or contracted depending on whether you include closely managed facilities that occasionally host charter or seasonal services. In practice, the most widely accepted count recognises nine airports on the island that regularly handle passenger traffic across Northern Ireland and the Republic of Ireland. These nine are the principal gateways most travellers will encounter when planning trips that cross the border or fly within the island.
The island of Ireland at a glance: nine public passenger airports
Across the whole island, nine airports are regularly involved in public passenger transport. These are distributed between the Republic of Ireland and Northern Ireland, reflecting the political border while illustrating a shared aviation landscape. The nine airports are:
- Dublin Airport (DUB)
- Cork Airport (ORK)
- Shannon Airport (SNN)
- Ireland West Airport Knock (NOC)
- Kerry Airport (KIR)
- Donegal Airport (CFD)
- City of Derry Airport (LDY)
- Belfast International Airport (BFS)
- George Best Belfast City Airport (BHD)
Notes on the list:
- Dublin is the island’s primary international gateway and the busiest in the country, handling a large proportion of Ireland’s international and domestic traffic.
- Cork and Shannon are the next‑largest gateways, with a mix of short‑haul European, UK, and some longer routes, depending on the season and airline schedules.
- Ireland West Airport Knock is a well‑established regional hub in the west, offering a selection of international and domestic routes, principally to the UK and mainland Europe.
- Kerry and Donegal airports are smaller, serving more regional demand and often acting as feeders to larger hubs via Dublin or Belfast, with some seasonal or niche services.
- City of Derry (LDY) and the two Belfast airports (International BFS and City BHD) cover Northern Ireland’s air travel needs, with BFS serving long‑haul and European routes and BHD focusing on short‑haul and regional connections.
Beyond these nine, there are other airfields around the island used for general aviation or occasional charters. These facilities are essential for local aviation communities and emergency services but do not feature regular passenger timetables. If your travel plan counts only airports with scheduled passenger flights, the nine listed above are the principal players for the island of Ireland.
Republic of Ireland: major gateways and their roles
The Republic of Ireland is home to several major airports that serve international, transatlantic, and European routes. The arrangement of these airports mirrors population centres, tourism demand, and the practicalities of air traffic management across the Irish Sea and the Atlantic corridor. Here’s a closer look at the primary ROI airports and how they contribute to the question, “How many airports in Ireland?” when considered on the island as a whole.
Dublin Airport: the dominant hub
As the Republic’s largest and busiest airport, Dublin Airport acts as the central hub for international travel, with a vast array of routes across Europe, North America, and beyond. It is the principal entry point for many visitors to Ireland and a crucial departure point for Irish residents traveling abroad. From Dublin, you can connect to major cities across the UK and Europe in a matter of hours, and on a clear day, the airport buzzes with the rhythms of a major international gateway.
For travellers counting how many airports in Ireland offer long‑haul or high‑volume international traffic, Dublin is the heavyweight. Its scale supports a broad mix of carriers, including legacy airlines and low‑cost carriers, and its position on the east coast makes it an ideal base for onward connections to destinations around the world.
Cork and Shannon: regional powerhouses with diverse routes
Cork Airport serves the southern region with a combination of UK and mainland European destinations, plus seasonal routes that respond to tourism demand in the southern counties. Shannon Airport, historically significant as a transatlantic departure point, remains a strategic facility for European and Atlantic traffic, with business‑oriented routes and a focus on efficient passenger experience. Both airports contribute to the answer of how many airports in Ireland by adding essential regional connectivity beyond Dublin, ensuring that the island has multiple arterial routes for travel across the country and across the sea.
Ireland West Knock and regional access
Ireland West Airport Knock (often simply called Knock) sits in the western belt, serving counties such as Mayo, Galway, and Sligo. The airport supports a practical mix of routes to the UK and mainland Europe, acting as a critical gateway for the western seaboard. For people asking, “How many airports in Ireland offer regional access for western counties?” Knock is a clear answer, representing a deliberate strategy to distribute air transport access more evenly across the island.
Donegal and Kerry: smaller but significant
Donegal Airport’s role is strongly tied to its northern western location, providing a convenient link for communities along the north‑west coast and neighbouring regions. Kerry Airport, similarly sized, focuses on domestic and short‑haul European services, often pairing with seasonal demand tied to the tourism calendar. These smaller facilities illustrate that even when considering the total count of airports in Ireland, scale varies—yet they remain essential for regional mobility and economic development.
Northern Ireland: three airports that balance cross‑border travel
Northern Ireland contributes three publicly accessible airports to the island’s air network. Their placement is strategic for cross‑border travel, tourism, and business, complementing the Republic’s gateways and enabling smoother connections for people and goods across the border.
Belfast International Airport (Aldergrove)
Belfast International is the larger of the two Belfast airports and handles a broad mix of European routes, seasonal charter services, and a gateway to the north of Ireland. It often serves as a practical alternative to Dublin for travellers coming from or heading to Northern Ireland, as well as for international visitors seeking efficient access to Northern Ireland’s key regions and cities.
George Best Belfast City Airport
Belfast City Airport (formerly known as George Best Belfast City) tends to concentrate on short‑haul routes, primarily within the British Isles and a few European destinations. Its narrow‑bodied aircraft operations and proximity to the city centre make it an attractive option for business travellers and short city breaks, contributing to the overall count of How many airports in Ireland by offering a convenient, city‑adjacent option for domestic and cross‑border trips.
City of Derry Airport (LDY)
City of Derry Airport, located near Londonderry, serves as a regional hub for the north‑west. It connects communities to key UK and occasional European destinations and remains an important facility for the North West region’s aviation needs. When assessing the island’s total airport count, City of Derry adds to the Northern Ireland tally and helps explain how cross‑border traffic patterns shape travel options.
How many airports in Ireland? Practical counting and traveller considerations
When people ask, “How many airports in Ireland are there?”, the straightforward answer is nine public passenger airports on the island that regularly handle passenger traffic. However, the nuance lies in definitions: some facilities are small, seasonal, or not currently operating regular passenger services, and others function primarily for general aviation or cargo. If you count only those with a sustained schedule of passenger flights, the list remains nine; if you include every airfield used for aviation, the total on the island rises beyond nine, though those additional sites do not serve standard passenger routes.
For travellers, the important takeaway is that there are multiple hubs across the island, each with its own strengths. Dublin provides the widest range of international connections, while Cork, Shannon, Knock, Kerry, and Donegal offer regional access that reduces travel time to specific parts of the country or to Europe. In Northern Ireland, Belfast International and City Airport, along with City of Derry, provide cross‑border and UK connectivity that is practical for domestic travel or business trips that prioritise proximity to major towns and cities.
Count by category: how the airports contribute to the journey
To understand how many airports in Ireland truly serve passengers, it helps to break down by category and audience:
- Major international gateway – Dublin, the hub for long‑haul connections and a large roster of European and domestic routes.
- Regional gateways – Cork and Shannon, with diverse schedules that cater to domestic Irish travel and international visitors exploring the south and midlands.
- Regional western hub – Knock, serving the western seaboard and offering a pragmatic route mix for travellers in the west and north‑west.
- Smaller regional airports – Kerry and Donegal, providing essential but smaller networks and some seasonal or niche itineraries.
- Northern Ireland cross‑border gateways – Belfast International and George Best Belfast City, plus City of Derry, enabling practical cross‑border access and UK connections.
In practice, this framework helps answer How many airports in Ireland are relevant for planning most trips: nine public passenger airports on the island act as the backbone of air travel for residents and visitors alike. The remainder of air facilities in Ireland primarily serve general aviation or occasional charter flights and do not form part of typical itineraries for a standard holiday or business trip.
Practical planning: choosing the right airport for your trip
When you’re planning travel, a few practical questions determine which airport to use. Here are some quick pointers to help you optimise your options and avoid unnecessary detours.
- Destination and connections: If your final destination is Dublin or a city well served from Dublin, it’s often easier to fly into Dublin and connect domestically within Ireland or onward to international hubs. For western or southern trips, Knock or Cork might offer more convenient options.
- Flight frequency: Larger airports like Dublin generally have more frequent services, including budget and legacy carriers. If you’re aiming for a quick domestic hop, smaller regional airports can offer direct options with shorter check‑in queues and easier security lines.
- Seasonality: Some routes are seasonal, particularly to holiday destinations in southern Europe or the Mediterranean. If your travel spans peak holiday times, check which airports will have flights to your destination in the exact week you’re planning.
- Accessibility: The distance from your home to the airport and the accessibility of public transport from the airport to your final destination can be as important as the destination itself. Regional airports can be wonderfully convenient for local areas but may offer limited onward options compared with Dublin.
Remember that travel plans can be affected by weather patterns, airline schedules, and temporary route adjustments. Keeping an eye on official airlines’ route maps and the airports’ advisories can save you time and keep your plans flexible.

Beyond passenger traffic: other aviation activities on the island
While this guide focuses on airports that carry regular passenger flights, it’s worth noting that Ireland’s aviation ecosystem includes other elements. General aviation facilities, private flight schools, air ambulances, and military airbases contribute to the broader picture of aviation activity on the island. These facilities do not typically appear in passenger traffic counts, but they are essential for medical transport, emergency response, crop dusting, law enforcement, and regional connectivity through non‑scheduled air operations.
Tips for travellers exploring multiple airports on the island
- Plan multi‑airport itineraries with care: If your trip involves moving between Dublin and Belfast or between regional hubs, check rail and road connections as well as flight schedules. A carefully planned multi‑airport route can save time and reduce travel fatigue.
- Be mindful of transfer times: Scenarios involving international to domestic transfers typically require longer layovers at larger airports. Factor in security, baggage reclaim, and terminal changes when calculating layover durations.
- Consider luggage handling and terminal layouts: Some smaller airports have simpler layouts and quicker security, but connections may require longer walking distances or shuttle services between terminals or car parks.
- Monitor seasonal variances: Certain routes expand or reduce their frequency with the seasons. If you’re planning a trip to the west coast or a holiday in southern Europe, verify current timetables closer to your departure date.
- Use official sources for updates: The best sources for accurate flight and airport information are the official websites of the relevant airports and the airlines themselves. They provide timetables, terminal details, and any notices that could affect your journey.
