i didn't get pretty well too when i operated ERJ-145LRs out of Spokane, WA and finally, i went bankrupt because the cost of operating is just killing me. they say Saab 2000s will do well on regional routes, and it does. now i have 4 of them and i started to make money.
but the range of Saab 2000 is just ~800nm, so i don't have much route option to be opened, and therefore, i need planes with 50 seats or so but with more range, and unfortunately the plane option is not pretty well too. so, any of you can successfully run regional airline with profitable jets? if so, what jet?
