Cheap Flights To Brussels (BRU) | 2026 Deals, Routes & Tips

Finding Cheap Flights To Brussels

Brussels is served by two main airports: Brussels Airport (BRU), the primary full-service hub, and Brussels South Charleroi Airport (CRL), a major base for low-cost carriers. This dual-airport system creates a highly competitive arrival market, making Brussels one of Europe's best cities for finding affordable airfare from destinations across the continent and beyond — provided you know which airport to target.

Travelers flying into Brussels consistently find excellent deals on a wide range of routes. At BRU, key affordable arrival destinations include major European capitals like London (LHR, LGW), Amsterdam (AMS), Frankfurt (FRA), and Paris (CDG), as well as long-haul hubs in Africa (Casablanca, Dakar) and North America (New York JFK, Washington IAD). At CRL, ultra-low fares are common from Mediterranean holiday spots (Alicante, Malaga, Palma), Eastern European cities (Warsaw, Budapest, Sofia), and secondary cities across Europe (Manchester, Edinburgh, Marseille).

The competitive arrival landscape is divided by airport. Brussels Airport (BRU) is a hub for Star Alliance, featuring Brussels Airlines alongside major international carriers like Lufthansa, Turkish Airlines, United, and Air Canada. Fares into BRU are generally higher but offer more connections and better intercontinental service. Brussels Charleroi (CRL) is dominated by Ryanair and Wizz Air, which drive prices down with aggressive sales from dozens of European cities. This split ensures fierce competition on many overlapping destinations — for example, you might find a Ryanair flight to CRL from Milan for €20 or a Brussels Airlines flight to BRU from Milan for €80. The choice depends on your budget and how close you need to land to the city center.

The best strategy for cheap flights to Brussels is to always search both BRU and CRL for your origin city. Book European arrivals into CRL several weeks in advance and watch for Ryanair's weekly promotions. For long-haul and business arrivals into BRU (e.g., from the US, Asia, or Africa), booking 2–3 months ahead and staying flexible with dates yields the best value. Note that Charleroi (CRL) is about 45–60 minutes south of Brussels by bus (around €17 one-way), while BRU is 15–20 minutes by train from the city center. If the price difference is small, BRU is more convenient; if you save €50+ by flying into CRL, the bus transfer is usually worth it. Using Belgium's excellent train network to access both airports easily expands your options.
