Referring back to the BHD-BFS link, this was part of a Gill Air daily shuttle which had multiple short sectors on an ATR: MME-NCL-BHD-BFS-NCL-MME. I once flew back from BHD to NCL and discovered that a colleague was booked on the BFS - NCL-MME sectors, but Gill Air wouldn't let him rebook ex BHD because "it's full". I was one of 3 pax who actually flew that sector in less than 5 minutes.
