Not really an upgrade, just a seat with more legroom. If you've been watching for more than a week or so, you've probably seen the full range of prices UA will offer. You will not earn miles on the purchase.
$99 seems steep for that flight (which is under 4 hours). You might get offered a buy-up to first class in the same price range. That would be a better deal.
