If you are a government flyer, and UA is big on government contracts, and if you can get by wasting taxpayer money by consistently booking into YCA rather than VCA, you would have some pluses in the new CR1 allocation: Class-of-service miles did not count towards the 10K quarterly minimum, and now you'd only need 16.7K BIS and would not have to worry about timing to get the CR1s after 75K. Also, big business class spenders, as noted before, has less of an incentive to book into United (CR1s and 1mm uncertainty).
