I had a broken Biz seat (787 the older 6 across type) would not recline FRA-SFO. It can be manually moved between upright and flat (but not in-between), and 3 FAs worked on my seat for over 20 minutes trying to get it working. I really appreciated the effort. The purser gave me $300 voucher in the air. I took it. I probably could have done better but oh well. I'm 1k MM.
