Giving Up on United Airlines and Mileage Plus

I'm breaking my hiatus, momentarily, to publicly register my dissatisfaction with United Airlines' Mileage Plus program, of which I have been a member for more than a decade. It was once fairly easy to use miles obtain upgrades on United flights, including to Europe. Now, it is nearly impossible. Even when seats are available, they charge a ridiculous premium on top of the already over-priced upgradeable coach fare. United upgrades are no longer worth the effort and cost. Consequently, I will be cashing in my miles for whatever crap I can get, then cancel my Mileage Plus membership and my United Visa Card.
