Cheap flights from Dublin to Belfast

Book a few weeks ahead and keep November in mind: it is the cheapest month on this route, with fares listed for September through February and again in spring and summer. School holidays and the weeks around Christmas push prices up, so if your dates are fixed, paying attention to the calendar matters more than the day of the week.

The mix is mostly full-service: Aer Lingus and British Airways operate with their regional arms BA CityFlyer and Emerald Airlines, while Loganair Limited and KLM Royal Dutch Airlines with KLM Cityhopper route you through their own hubs. No carrier flies direct, so every itinerary includes a layover, and the fare usually covers a cabin bag and checked baggage. That makes the base price a poor guide — check what is bundled in before comparing.

You land at George Best City Airport, which sits right beside Belfast and a short ride from the centre. Buses and taxis are the usual ways into town, and because the airport is close in, the transfer is quick by UK standards. Watch your arrival time: a late connection can leave you relying on a taxi rather than the bus.

Country facts: Wikidata

• Confirm your departure airport, since Dublin is the only one listed here and it differs from other cities where two airports compete.
• Check baggage allowances with the carrier you pick, since fare bundles differ between Aer Lingus, British Airways and the regional operators.
• Verify passport and entry requirements for travel into the United Kingdom before you pay.
• Look at the layover length and whether connecting flights are on one ticket or two.
• Compare November fares against summer dates in the price calendar to see the seasonal gap.
