The CR2s (50-seaters in general) are not scope-limited and UA can fly as many of these as it wants to. The Air Wisconsin contract is apparently quite flexible and can be drawn down at pretty short notice. United is trying to increase connectivity at its hubs and the CR2s will predominantly be used in short, less-competitive markets to bring higher-yielding pax to the hubsites for distribution around the network. Kirby is convinced that United's relative disadvantage in terms of hub quality to AA/DL is partially responsible for United's revenue and marginal underperformance.

My guess is part of the deal ensures Air Wisconsin will be the first in line to operate new large RJs if United is able to negotiate scope relief from the pilots.
