Airports: Barajas, Zaventem, and Charleroi (choose wisely and save)

Picking the right airport can save you a lot — both on the ticket and on the ground.

Madrid-Barajas (MAD)

The single departure point. T4 is Iberia and its partners’ base (including codeshare Brussels Airlines); T1/T2/T3 handle the rest (Ryanair, Vueling, Transavia). If you’re connecting, leave margin between terminals.

Brussels Airport / Zaventem (BRU)

Belgium’s main international gateway, located about 15 km northeast of Brussels city center. It’s the most convenient option:

• Train to the center: direct rail from the airport station to Brussels-Central or Brussels-Midi in ~20 minutes. Trains run several times per hour.
• Connections: ideal if you’re continuing to other European cities (Amsterdam, Cologne, Paris) via high-speed rail.
• Services: extensive shopping, dining, and lounge facilities.

Brussels-Charleroi (CRL)

Located about 50 km south of Brussels, this secondary airport serves mainly low-cost carriers:

• Shuttle bus: ~45–60 minutes to Brussels-Midi (South station). The ticket costs around €15–18 one way.
• Pro: airfares are often cheaper than flying into BRU.
• Con: the time and cost of the airport transfer can eat into your savings.

Often-forgotten tip: the cheapest ticket isn’t always the cheapest overall

Add the airport-to-center transfer and baggage before deciding. A flight that’s €15 more expensive into BRU Zaventem can actually work out cheaper if you save €20 on the train vs. bus fare from Charleroi. Always factor in the full journey cost.

When is the cheapest time to fly to Brussels?

Data from search engines like Skyscanner, KAYAK, and Google Flights agree on the lowest-demand (and therefore cheapest) months:

• January — the cheapest month on average. Demand collapses after the Christmas and New Year period.
• September — the second half is ideal: summer crowds thin out, prices drop, and the weather stays pleasant.
• February and March — also affordable, except during school breaks and European Parliament sessions.

When to avoid: July, August, and peak business travel periods (key EU parliamentary sessions drive corporate demand). Also avoid holiday peaks — Christmas, Easter, and May bank holidays. If summer is your only option, fly mid-week and book well in advance.

7 real tactics to get the cheapest flight

1. Fly Wednesday or Thursday. The cheapest days of the week; weekends always cost €20–40 more on average.
2. Book 1–3 months ahead. Not too early, not last-minute: that’s the sweet spot for European routes. (Learn more in our guide on how far in advance to book a flight.)
3. Compare BRU vs CRL. Flying to Charleroi can be cheaper, but only if the transfer cost doesn’t cancel out the saving.
4. Consider strategic stopovers. Occasionally a connecting flight via Munich or Zurich works out cheaper than a direct one.
5. Stay flexible on dates. Shifting by a day can save 20–30%.
6. Travel light when you can. Low-cost carriers discount the base fare; checked bags cost extra.
7. Use a metasearch that groups every airline. The fastest way to never miss a deal. For more tactics, read our tips to find cheap flights that actually work.
