HN is a Standard Award for economy -- only upgradeable with cash buyup. It may be offered at booking, at OLCI, at the airport or it may not be offered (if offered likely to >$800-1,200 OW). Mileage upgrades on award flights are not possible.

The miles required are still as I noted. The extra cash is what differs based on fare class.
UA does 1 non-stop flight daily year round SFO-FRA (744) and 2 flights daily late Apr-late Oct. SFO-FRA has long been a cornerstone UA flight offering.
