Amtrak and United BOTH knew about this in time to announce it before it happened. Their failure to do so was unconscionable. This gives me a lasting ill will toward both programs. I had recently made United my ''second choice'' airline after NW. No more! I have less trust of them than any other airline ff program as a result of them blindsiding their members on this.
Extremely poor consumer service for both of them.

I don't necessarily blame them for the change itself. Partnership arrangements do change from time to time. But not announcing it ahead of time, like other carriers routinely do, is another matter entirely!
These scoundrels do not deserve our business.
