Alternatively, one can book the LH codeshare flights on United.com, and then call United reservations and request that the flights be changed to the direct Lufthansa flights. This is the procedure for making the flights eligible for applying GPUs to Lufthansa flight. A GPU can only be applied to a direct LH flight number, so the codeshare flight must be exchanged for the direct Lufthansa flight, and then the GPU can be applied.
