Cheap flights from Belfast to Brussels

The weeks on either side of the post-holiday lull are where fares often soften, and February is the cheapest month in the listed range. December and the run-up to Christmas push prices up, while October and November are often calmer before the winter peak; March and April then lift again as spring travel begins. Midweek departures usually face less pressure than weekend ones, and the time of day can decide which connection you are offered. Check school holiday calendars in both Belfast and Brussels, because family and business travel can tighten the same flights.

The real difference a traveller feels is not the airline name but what the fare includes, because the same route is sold with very different baggage, seat and change rules. No listed airline flies this route non-stop, so every itinerary has at least one connection, and some bookings may be separate tickets rather than one protected journey. BA CityFlyer, British Airways, KLM Royal Dutch Airlines, Aer Lingus, Easyjet and Emerald Airlines all appear on the route, but the conditions attached to each fare are what you should compare. Read the small print before you assume a cabin bag or a seat is included.

Brussels Airport is a large international airport, so allow time for walking, security and baggage reclaim, and treat the transfer into the city as part of the journey rather than an afterthought. The usual options into Brussels are rail, bus and taxi, and the best one depends on where you are staying and how much luggage you have. Watch for terminal and gate changes on arrival, and keep your documents handy if you are connecting onward. If your flight lands late, check the last public transport times before you rely on them.

Country facts: Wikidata

• Check whether your itinerary is one ticket or separate tickets, because a missed connection on separate tickets is your own problem.
• Confirm the connection time is realistic for the airport you are changing at, not just the minimum shown.
• Read the baggage rules for each airline on the booking, especially if a low-cost fare is involved.
• Make sure your passport and any visa or entry requirements for Belgium are sorted before you pay.
• Check that your ticket names George Best City Airport, the Belfast airport used on this route.
• Look at the month and day of travel against school holidays in both countries before you commit.
