From Hasselt you have more choice than you might think. Maastricht Aachen Airport is about 44 km away, Liège Airport about 54 km and Eindhoven Airport about 70 km. Brussels Airport is roughly 55 minutes away without traffic. People in the capital of Limburg province often pick the airport with the best flight, then book an airport taxi to get there.
With Offerly you describe your ride once, and checked taxi firms, private drivers and minibus companies send you an offer. You compare price, vehicle and payment method, then choose. Requesting and comparing is free and without obligation, and no account is needed: you receive an email with a personal link.
Closer to home there is plenty of demand too: rides to the station, to Jessa Hospital, to a lecture at UHasselt in Diepenbeek or to a festival weekend. You pay the company you choose directly, and you can cancel through your link as long as the time of the ride has not passed.
