Choosing the "better" airport in Brussels depends entirely on your airline choice and final destination. Brussels Airport (BRU), located in Zaventem, is the primary international hub and is generally considered superior for most travelers. It is situated just 12 km from the city center, with a direct train link taking only 15 minutes. It hosts legacy carriers, offers extensive lounge facilities, and has a vast array of dining and shopping options. In contrast, Brussels South Charleroi Airport (CRL) is primarily a hub for low-cost carriers like Ryanair and Wizz Air. While it often offers significantly cheaper flights, it is located roughly 46 km south of the city. Reaching central Brussels from Charleroi requires a 55-minute shuttle bus or a combined bus-and-train journey, which can be cumbersome. If convenience, proximity, and amenities are your priority, BRU is the clear winner; if you are a budget-conscious traveler willing to trade time for lower airfare, CRL serves its purpose well.
