Curious as to what you mean by "cheap".....fuel/lease/pilot/crew...costs.....and by "cheap" are you comparing it to DASH...737 320????......
We use the 145,s(plus other models of ERJ) on short runs to supplement our main carrier,because they have become economical(not cheap) on the short runs as the load factors are such that a 70-90 pax aircraft does the job......but the costs to run them are compable to some of the mainline fleet(73,s 319/320,s) and the only thing really "cheap" on the ERJ....is what they pays their crews
Not trying to shoot holes in your post,trying to figure out your "cheap" theory
