Also scope clause is a factor and legit argument for the 200 to stay, but it’s probably being renegotiated as we speak. United could decide that protecting a slot with a little 200 on an unprofitable route makes long term sense, OR they could let routes go like they have in the past. They could also go for reduced frequency on larger aircraft, which reduces the demand for slots. I personally believe the future of 200 is dictated on protecting or not protecting slots, not scope.
