SanDiego1K,
Thanks for these data points, observations and conclusions. I can confirm, when redeeming UA/MP miles for Star Alliance awards that:
- LH always seems to have F/C seats, and UA does not.
- LH seems to offer the same award inventory through UA/MP as they do through M&M.
I'm wondering if you had any conversations re: the "90-day limit" on transatlantic travel on LH when using UA/MP miles?
