I just checked this websiteketambe.com/ketambe_how-to-reach.html
and discovered the flights have resumed.
So all you lucky travellers planning on heading down to Ketambe via Kutacane can now enjoy a short flight instead of the 7-8 hr bus trip.
How I wish the flights had been operating when I was recently in Indonesia.
I never made it to Ketambe because I got sick and the thought of an 8 hr bus trip was too horrendous to think about after an afternoon in hospital on a drip.
