The point of E175s is the higher yielding passengers from smaller destinations. If anyone doubted this before, here’s your proof.
The CRJ550 takes care of the premium pax while leaving a few low yielding passengers behind. Not ideal, but it is a workaround scope.
If this is successful it’ll render scope nearly useless. Given the higher costs I’d expect limited use/success of these aircraft. However it is a threat and it will reduce bargaining power re:scope clause. Relief still won’t happen, but it’s gonna make bringing 175s in-house more difficult for ALPA.
