Belfast International vs Belfast City: the quick verdict

If you live in or near Belfast and want the cheapest way out, Belfast International is usually the first airport to search. It is the bigger airport by a distance: the Civil Aviation Authority recorded 6.74 million terminal passengers there in the twelve months to May 2026, against 2.43 million at Belfast City. More of those seats are low-cost holiday flights to Spain, the Canaries, Portugal and further afield.

Belfast City wins on convenience. It sits about three miles from the city centre, so a 7am flight is far less painful if you live in east Belfast or North Down. Its network leans towards Great Britain: London, Manchester, Edinburgh, Glasgow, Bristol and smaller regional airports, plus KLM to Amsterdam.

So the honest answer to “which Belfast airport is cheaper?” is: for a beach holiday or a European city break, BFS almost always has more options and so more chances of a low fare. For a weekend in London or Manchester, search both and let the total cost decide. For long-haul, or a route neither airport serves, add Dublin to the list.

BFS, BHD and the booking mix-up to avoid

Two airports in one small city means mix-ups. Belfast International is BFS. George Best Belfast City is BHD. Some booking screens just say “Belfast”, and Belfast International is often called “Belfast Airport” on its own, which does not help.

The mistake is expensive in practice rather than on paper. Book an outbound from BHD and a return into BFS and you could land at night on the wrong side of the city from your car. A friend collecting you might drive to the wrong terminal. Read the three-letter code on the search result, on the airline’s checkout page and on the confirmation email.

Mixing airports can still be a good idea. Flying out of Belfast City on a Friday evening and back into Belfast International on Sunday is fine if you are using buses or a taxi. Just make it a deliberate choice. Our guide to searching multiple airports in Google Flights shows how to put both codes in one search.

Who flies from each Belfast airport

Belfast International. easyJet flies the widest spread of routes in our BFS data, from domestic hops to winter sun. Ryanair said in July 2026 that it has two aircraft based at the airport and operated 15 routes that summer, naming Alicante, Lanzarote, Malta, Kraków, Milan and Porto. Jet2 runs flights and package holidays from BFS, and Jet2holidays lists more than 24 destinations there, including Menorca, Fuerteventura, Gran Canaria and Crete. Visit Belfast also lists TUI at the airport.

Belfast City. Visit Belfast lists Aer Lingus Regional, British Airways, KLM and easyJet at George Best Belfast City. easyJet flies from there to Bristol, Edinburgh, Glasgow, Liverpool, London Gatwick, London Luton and Manchester, and is adding London Southend three times a week from 25 October 2026. Aer Lingus Regional and British Airways add more domestic choice; check their own sites for the current Belfast City timetable, because routes change between seasons.

Airline mix is the main reason fares differ. Ryanair and Jet2 are not on Visit Belfast’s list of Belfast City airlines, so if you want a Ryanair fare to Alicante or a Jet2 package to Lanzarote, BFS is where they are. If a low headline fare depends on a budget airline, check what you will pay for bags first: our guide to budget airlines covers the trade-offs.

What Blame the Fare's BFS deal data shows

Between 19 September and 17 October 2026, the scanner logged 504 BFS deal observations across 39 destinations. Every one was a nonstop return in economy for one adult. easyJet appeared on 29 of those 39 routes, Ryanair on eight and Jet2 on seven. Fifteen routes had at least one fare under £50 return.

A few patterns stand out. Short Ryanair hops such as Paris Beauvais kept appearing close to departure, with a median of eight days between sighting and flight. The winter sun and ski routes looked different: Lanzarote, Marrakesh and Geneva deals were mostly for flights two to three months out. Prague deals were for departures a median of 105 days ahead. This does not prove when booking is cheapest, because the scanner only records fares flagged as deals. It does show that useful BFS fares turn up both last minute and well ahead.

In the feed on 17 October 2026 there were 18 BFS deals. The cheapest was £41 return to Leeds Bradford on easyJet (2 to 5 November), with £45 to Málaga on Ryanair (13 to 16 December) and £49 to both Lanzarote and Alicante. The median of those 18 was £69.50, and the most expensive was £163 to Hurghada. The median fare sat about 52% below the typical price the provider showed for each route. You can see the current preview on the Belfast International flights page.

Flights to Great Britain: where the airports overlap

This is where the choice gets genuinely close. easyJet flies to Bristol, Edinburgh, Glasgow, Liverpool, Gatwick, Luton and Manchester from Belfast City, and it also flies domestic routes from Belfast International. Aer Lingus Regional and British Airways add more choice at BHD.

From BFS, the scanner logged 42 deal observations to six Great Britain airports in the four weeks to 17 October 2026. Glasgow, Liverpool and Newcastle each had a lowest logged return of £33, Leeds Bradford £37, Bristol £38 and Southampton £44. Some of those are thin samples (Bristol was seen once, Newcastle and Liverpool twice), so treat them as proof that fares at that level appear, not as a typical price.

For a short domestic trip, the airport transfer can be a big part of the cost. A slightly higher fare from Belfast City may still work out cheaper once you price the shorter bus ride or taxi. If you are flying to London, also check which London airport you land at; our guide to the cheapest airports to fly from explains why the airport, not just the fare, matters. Departure pages for Gatwick, Luton and Manchester show what is onward from there.

Getting there: the 300 and 600 buses

Translink runs a dedicated airport bus to each airport. The Airport Express 300 links Belfast International with the city centre, and the Airport Express 600 links Belfast City Airport with the city centre. Tickets for both can be bought at Belfast Grand Central Station and from machines at the airport bus stops.

Visit Belfast describes Belfast International as a 30-minute drive from the centre and Belfast City as three miles away. In practice, that difference shows up most on early flights: a 6am departure from BFS means a very early start if you are relying on the bus. Fares and timetables change, and sources disagree on current prices, so check Translink’s journey planner rather than trusting an old figure.

If you are driving, compare parking at both airports for your dates before you book flights. A week of parking can easily cost more than the gap between two fares. If you live in the north or west of Northern Ireland, BFS may simply be closer, and the Belfast City convenience argument disappears.

When Dublin Airport is worth comparing

Dublin Airport has a far bigger network than both Belfast airports combined, including transatlantic flights. It is worth checking when:

• you are flying long-haul and would otherwise connect through London or Amsterdam;
• your destination has no direct flight from BFS or BHD;
• you are travelling on dates when Belfast fares are high, such as school holidays.

The cost is time. Visit Belfast puts the coach journey from Dublin to Belfast at approximately two hours. The Translink and Bus Éireann X1 serves Dublin Airport, and Aircoach’s 705X links Belfast Grand Central with Dublin Airport and Dublin city centre. Add two coach fares, the risk of a delayed coach before an early flight and possibly a hotel. A Dublin fare needs to be meaningfully cheaper to be worth it for a short European trip. For a long-haul family trip the saving can be large enough to justify it.

Blame the Fare does not scan Dublin, so compare it in a normal search tool. If you are weighing longer trips to reach a cheaper airport, our guide to positioning flights covers the risks of separate tickets.

Passports, photo ID and the Common Travel Area

Flights from Belfast to Great Britain are domestic, but that does not mean no ID. Check which photo ID your airline accepts before you go.

Dublin is different, because flights from there to Britain cross an international border inside the Common Travel Area. The UK government’s guidance says British and Irish citizens can move freely between the two countries and do not need a visa or permit to enter the UK. Other nationalities remain subject to immigration rules and should check whether they need a UK visa when travelling from Ireland.

Airlines can set stricter rules than the law. From 25 February 2026, Aer Lingus has required all passengers, including British and Irish citizens, to carry a passport or Irish passport card on flights between Ireland and the UK; other photo ID is no longer accepted. Take your passport if you plan to fly from Dublin, and check the rules for the airline you book.

How to price a trip across BFS, BHD and Dublin

1. Decide whether the trip is BFS-only. For a Ryanair or Jet2 destination, Belfast City will not have it. For Great Britain, include both codes.
2. Search both airports on the same dates. Use the same passengers, cabin and bags so the fares compare like for like.
3. Add the getting-there cost. Bus, taxi or parking, both ways. For Dublin, add the coach and a buffer for delays.
4. Price bags at checkout. Low-cost fares often exclude a large cabin bag or hold bag; see our checked bag fee guide.
5. Check the airport code on the booking. BFS or BHD, on both legs, before you pay.
6. Set an alert for the route you settle on. If the fare is close to your limit, watching it beats re-searching daily.
