Your question is fair but the answer has not been volunteered.
I spoke with a Royal Brunei F100 pilot a number of years ago who made an off the cuff comment that he understood the aircraft were expensive to own and operate. If I remember correctly he said the aircraft were in good condition and were ex Swissair.
Royal Brunei used the F100 while in their fleet (for a brief period only) on both short and medium range sectors in S.E Asia. I saw the a/c in BKK on one occasion and both SIN and KUL a number of times.
I guess BBK would be a good 3 hours in nil wind/weather conditions from BWN.
