If DayJet couldn't make it, it ain't possible, IMO. Florida is a perfect Petri dish for this type of operation, the Eclipse might have been a good fit,butnot so much success. Florida has lousy intra-state commercial connections, lots of inter-city day travel and everyone has failed trying to meet what looked like ready demand. In Florida, it's been tried by everyone from majors to Cirrus planes. Not optimistic.
