The itinerary MUC-SFO-YVR-SFO-LAX-NRT-SIN-MEL-SYD is appeared in UA "My Itineraries" page; as well as the E-tix info, eventhough the FF# appeared is for SQ. The SFO-JFK-SFO was booked in different PNR, because of SQ systems did not show any availabiliy in A for those routing, and the gent had to book to UA directly.
