Brussels is served primarily by Brussels Airport (BRU) in Zaventem and the smaller Brussels South Charleroi Airport (CRL) near Charleroi. BRU functions as Belgium’s main international hub and typically handles most full-service carriers and many long-haul flights; fares there can be mid-to-high relative to budget alternatives. It lies about 12–20 km northeast of central Brussels, reachable by train in roughly 20 minutes (moderate fares) or by taxi in 20–30 minutes (higher cost). Charleroi is positioned as a low-cost secondary airport, mostly used by budget carriers and seasonal services; it’s farther out—around 45–60 km—and usually requires a coach shuttle of 50–80 minutes or a longer taxi ride. BRU offers greater comfort and frequency, while Charleroi can be cheaper but less convenient for quick city access.

Istanbul’s two main airports serve distinct roles: Istanbul Airport (IST) is the city’s large international hub, handling long-haul and many full-service carriers, while Sabiha Gökçen (SAW) is typically favored by low-cost and regional airlines. IST sits about 40–45 km northwest of the historic center; travel to the city can be by metro link, airport shuttle, taxi or private transfer, usually taking 35–60 minutes depending on traffic, with shuttles and public transit generally being the most economical options. SAW lies roughly 35–45 km to the southeast on the Asian side, reachable by Havatas/municipal buses, shared shuttles or taxis in 45–75 minutes; fares tend to be lower on buses but higher on taxis for cross-city trips. Pros: IST offers extensive international connections and modern terminals; SAW can be more convenient for travelers staying on the Asian side or seeking cheaper low-cost flights. Cons: both airports can involve long transfers to some central neighborhoods and may be affected by heavy traffic during peak hours.

In different months, ticket prices from Brussels to Istanbul vary: minimum — $59 (August 2026), maximum — $133 (July 2026). Typically, the flight costs $88–$169.
