I have heard from numerous sources that the revenue team really wants 83 seats in the CRJ-900 and E-175's to maximize their revenue generating capability. At Delta, 7 more seats is a big deal. They spend millions changing the configurations to maximize revenue. Couple that with the staffing problems they are having and I would also put money on the 76 seat fleet showing up at mainline. DCI will end up with the few 50 and 70 seat jets left....and maybe some T-props. I still think we will see Q-400's at DCI sometime.
