By train .... duh

Take the train

Take the international train from Amsterdam to Brussels, it leaves at 23 min after every hour. You have to change in Antwerp if memory serve, i've done it myself - it's a good connection.

By train:
- Amsterdam - Brussels: leaving every hour x.23 arrives x+3.14 (so 2h51 travel time) Normal price 33.40 euro
- Brussels - Charleroi Sud: 2 trains every hour, 50 minutes travel time, normal price 7.80 euro
- at Charleroi Sud you can take a bus to the airport

You can switch in one of the 3 Brussel stations (Nord, Central or Midi)
