Once that's done, apply your PlusPoints using the online tool--phone agents cannot do this.
That's exactly what I asked her to do -- convert the UA codeshare flight number for the LH flight into a LH flight number. She said shes never heard of it and needs to involve a supervisor. Been waiting for 45+ minutes now.
