Hard to say anything that hasn't already been said. While the loss of CR1's won't affect me that much, the increase in EQS is a slap in the face.
More than anything "lost" by the change - I think it's a sign of things to come.
While I will not rush out to find a new airline of choice, should E+ disappear any time soon, there would be no reason to continue any allegiance to UAL.
