Wouldn't it be nice if you could really use miles to book the whole flight with ZERO extra dollars? I spent a few years worth of miles to book this flight and it seems really tacky to have to pay cash on top of that, considering I pay an annual fee to use my MileagePlus Explorer card.

So for H, you can upgrade to Business Class for just $425 and no miles?
It sounds like the OP has award tickets in coach purchased with UA miles. This is very different from upgrading from tickets paid with money.
