There is a Miles&More helpline which can help in booking a domestic (USA) reservation using Lufthansa miles program. I just now tried to make a to-fro reservation from SFO to RDU (or to any of its neighborhood airports) for a trip on May 13th to 15th. The rep said they don't see any availability right now, but I can see availability on the United website. The rep further said in a couple of weeks United might release some tickets to its partners, and Miles&More might receive some of them. Does anyone have experience making domestic reservations on United or any other airline using Miles&More? When would be a good time to check back with them. I am planning to wait and check back with them, but if the said United tickets don't arrive at Miles&More, I will most probably end up doling out more for the same tickets later on.
