Lufthansa / United Code Share - how to upgrade with Star Alliance?
Need some advice please...on a Lufthansa flight (Doha-Frankfurt-Houston) that's a United codeshare. I'm United gold member and want to upgrade via Star Alliance. I called and they said to have the ticket reissued as Lufthansa, not United, but I'm not allowed to because of the government rules (foreign carriers). Any ideas on how to upgrade on a Lufthansa flight, using Star Alliance / United miles without the run around? Thanks!
