Haha, Comair did something similar years ago with the “40-seater” (CR4). They pulled 10 seats out of a CRJ200, built a big closet and carried 40pax. Bombardier even delivered new ones like that. It didnt last very long.
The irony is I think those old CR7’s at GoJet that will be converted to 550’s are old Comair (CA) planes, lol.
