Public Transport in Belgium = Disaster

My wife and myself  must take the plane at 11h00 in the morning, three hours in advance we must be on the  airport for a intercontinental flight .
From my hometown to Brussels airport the distance is 150 km. 

For this distance , We need two days with Public Transport .
In my village there is a bus twice a day to a city where we can take a train.  In the morning at 7h30 and on the evening at 16h30 . We cannot take the bus in  the morning because from the bus station to the railway station is about 1h00 drive . To late for a train to the airport because from the train station to the airport is 1h30min . We will arrived on the airport and we will find out that the plane is already left.

So : We must take the bus on the evening , find a place to sleep near the airport for the night.

Cost for this poorly developed public transport in Belgium : Bus = 5 Euro + Train to a Hotel = 54 Euro + Hotel = 60 Euro (Hotel not to expensive ,15km from the airport)  + Train to the airport next day = 36  Euro ( include special tax when you go to the airport with the train ) .
Total price one way  :   155 Euro ....... 

Conclusion :
For which reason we should take public transport in Belgium, always not available  and secondly  to expensive .
By car ( Taxi) , it is easy , a lot faster and a lot cheaper.

Welcome to Belgium.
