Hmm, looks like I have a UA numbered LH codeshare booked into UA R (deep-discount premium economy comparable to LH N) connecting to an intra-Europe sector booked into Q, also with a UA flight number and LH operation.

Am I out of luck for assigning seats unless I convince someone at UA to reissue the ticket with an LH flight number? Which could be a tough sell since the fare isn't PlusPoint upgradeable except on the intra-Europe sector?

edit: OK apparently LH is happy to assign seats on this premium economy sector on the codeshare for 50 USD, which is their published policy, https://www.lufthansa.com/us/en/sitz...meconomy-class . Wow.
