Well, whose fault is that? The OP?

Last month (or November, I forget exactly) when I on the line with a UA CSR, without any prompting from me whatsoever, I was advised by the CSR not to fly the first week of March, on account of that was when the SHARES transition was going to take place.

Now, that could have been the grumblings of a dissatisfied employee. But several PMUA CSRs have posted about SHARES as well, and they don't have very complimentary things to say about it.

Maybe everything will be rosy and bright come transition time. But given UA's continued silence about what functionality will and won't be available, you can't blame customers from being apprehensive.
