I've got a little more faith in XJT's management than you, apparently. Then again, I've actually worked under them before. You'd probably see more regionals striking out on their own if it weren't for one thing: branding. Regionals don't have to carry a marketing department, fare structure experts, etc, etc since mainline does all that for them. If you strike out on your own, that even more costs you're gonna have to take on. You can't just say "Well, if the routes were profitable, then more RJ operators would do their own thing." It's more complicated than that. You have to figure out how to get people on your plane. Dropping the mainline connection loses the website, 800#, frequent flier program, and (most of all) the name recognition. The marketing and the loss of passengers that don't recognize "Pinnacle' as a reputable airline but know "Northwest" pretty well would kill some of the most profitable routes since you've now got to absorb that marketing strategy into what profit there was. Then take into account that mainline carriers like NWA will take a loss on routes since they're big enough to count on more profitable routes subsidizing it in order to keep passengers, and it's a tough world. Ask Frontier how well their MEM flying is going. NWA launched what amounted to a "Oh no you don't" campaign against them when they started flying into MEM. As of JAN, the A319 is gonna be a thing of the past here. It's gonna be E170s. But, I guess according to your thinking a half full A319 would be more profitable than a full E170.....
