Just to clear this situation up, KathyWdrf , personally my E-Upgrade summary has not worked for over two months. I have checked at least twice a day every day for two months. I am very competent with websites and systems, and I have not been able to access this from any computer.
Judging from other responses, I am not the only one in this situation. As always, YMMV. Just consider that different people may have different experiences. And this downtime is a factor in the overall 20% figure. It is very rare for all of the important pieces of the United.com website to be working properly at any given time.
My company runs a very big website, and it is very rare for a single link not to function properly at any given time.
