Skytrans did many moons ago. Originally started in the Titan in the pre Dash 8 (and pre Wild) days and was quite popular. Later on it was turned into a Dash service and due to poor scheduling it's on time performance was appalling and became unpopular with very low pax numbers. Eventually this improved and it started to become popular again but just as this happened they decided to "redistribute" the aircraft to a mining contract, cancelled the service and never went back.
