Cheap flights Belfast to Paris

October is the cheapest month on this route, and the calendar shows fares easing again in late autumn and early winter once the Christmas rush is over. Summer school holidays and the Easter break push prices up on both sides of the Irish Sea, and half-term weeks in Northern Ireland fill seats quickly. Midweek is your friend: Tuesday and Wednesday departures usually cost less than Friday evenings or Sunday nights. Book a few weeks ahead for spring and summer travel, and if your dates are flexible, let the calendar choose the month rather than fixing the dates first.

Ryanair and Ryanair UK, easyJet and EasyJet Europe cover the low-cost end of Belfast to Paris, with unbundled fares where bags and seats are added at checkout. Aer Lingus, British Airways and BA CityFlyer are the full-service names, with more bundled into the ticket. KLM Royal Dutch Airlines sells connecting itineraries through Amsterdam rather than flying the route nonstop, and Emerald Airlines and Loganair Limited appear among the options too, so read the itinerary to see who actually operates your flight. Filter for direct departures if you want the shortest day; take a connection if the fare matters more.

Paris has three airports and they are not interchangeable. Charles De Gaulle lies north-east of the city and handles most of the full-service traffic, with trains and buses running into the centre. Orly is south of Paris and closer in, linked to town by an automated shuttle train and by buses. Beauvais Tille is the outlier: it sits well outside the city and is mainly reached by coach, so build in extra time if your fare lands there. Check the airport on your ticket before booking a hotel near a particular station, because a Beauvais arrival changes your whole transfer plan.

Country facts: Wikidata

• Check which Paris airport your fare uses, since Beauvais Tille is far outside the city and Charles De Gaulle and Orly are not.
• Confirm that you are flying from George Best City, the Belfast airport this route uses.
• On low-cost tickets with Ryanair or easyJet, price the cabin bag and seat you actually need before comparing totals.
• If you connect through Amsterdam with KLM Royal Dutch Airlines, check the layover length and whether your bags go straight through.
• Carry a valid passport and check the current entry rules for France before you fly.
• Use the price calendar: October is the cheapest month, while summer and holiday weeks cost more.
