I have just booked my flight to Sulawesi two weeks ago. I'll go in March with Singapore Airlines. Time schedule is: departure Amsterdam 10.30 arrival Singapore 5.55, departure Singapore 6.45 arrrival Jakarta 7.30, departure Jakarta 10.35 arrival Ujung Pandang 13.55. I have booked via Vliegwinkel. Price at time I booked was 1056 euro but I am flying back from Bali. There is also a KLM flight but than you will arrive around 0.30 in Ujung Pandang since I am travelling alone I did not want to take this flight. A couple of years ago (2007) I went from Amsterdam to Manado and there was only one stopover (in Singapore). Hope this helps.
