If the company brought on E195's would the min guarantee be based on Group I or II? We're going down a dangerous path asking for overrides like people wanted for the 321. Hell they could keep one E190, base all reserves and min guarantee off that, and have a bunch of E195's doing the majority of the flying.
This is why I support one rate across all fleets, with an override for international stuff because of the PITA factor of it.
