as long as the UA-LH-flight is a UA-flight-number (LH the carrier "only") you are promissed the full credits as on "proper" UA-flights (base-miles, class-bonus-miles, status-bonus-miles) but as a GENERAL RULE you will have to claim and proof it later (enclose ticket-copy stating the UA-flight-number and boarding-pass-copy) - till very lateley (and probably still now) the UA-flight-number is NOT LOADED on the LH-computers (only textwise). So as a general rule (happended to me and my wife overall 16 times in 1998) on UA/LH-flights you get the base-miles (and base-status-miles) and the class-miles creditet automatically, the status-bonus-miles only after you claim and proof it.
