Around 6km north of Charleroi, this is Belgium’s main hub for budget airlines, notably Ryanair. Two or three coaches per hour take 55 minutes to Brussels. Flibco (www.flibco.com) offers connections to Luxembourg, Bruges and Ghent. Bus A runs to/from Charleroi-Sud train station (€6, 20 minutes, free with train ticket, purchase bus-plus-rail ticket at airport).
The nearest of the generic airport accommodations is Ibis Budget, which, while physically close to the terminal, is actually 1.4km away by road.
