Actually, no, RJs do not hurt the major airline. RJs are necessary to carry passengers from small/medium spoke cities to the hubs. If it weren't for RJs small/medium communities that don't have the traffic to fill larger jets would be negatively impacted. Perhaps the question should be... with the current industry set-up do RJs hurt the PILOT profession? After all, we all do the same thing. Part of the problem is that WE foster the division. If that was the question... then YES. If the RJ was operated at mainline, we wouldn't be having this discussion. Pandora is out of her box now and it'll take lots of work and sacrifice to get her back in and get this mess under control. Who's going to blink first?
