I was able to find 2 biz award space on August 25 from Shanghai to Paris on LH729 and LH1050. However, the agent told they can not be booked because these seats are not actually available on either flight. I have used United.com, Aeroplan.com, and NH engine to "confirm" the availability.

Does Aeroplan really have less access to the Star Alliance？

Or is this an inventory issue caused by Lufthansa?

Another interesting observation is that it shows zero availability on LH1050 when I searched FRA-CDG, but it shows available when I searched PVG-CDG. Is this some kind of married award redemption policy imposed by Lufthansa?

Thanks for sharing your opinions!
