Ironically, had the RJX remained in production it would probably have done reasonably well. It fills a niche which a number of operators are having difficulty filling.The Embraer 145 series and Bombardier CRJs are fine for daytrip business travel, but their lack of volumetric capacity for baggage make them unsatisfactory in large areas of the world.( eg Asia, Africa, Middle East and use on holiday routes in Europe). The A 318 is very heavy for its capacity and only makes sense for operators of the larger models who want the economies of fleet commonality at the bottom end of their capacity range. The politics seem to be a long standing lack of real enthusiasm in BAe for the civil business , originally exemplified by their failure to fully develop or produce in sufficient quantities, the One-Eleven. 9/11 gave the excuse for a quick exit from the 146/RJX programme and they took it. As further evidence of their lack of interest in the civil side even their continued interest in Airbus seems to be in question.
