OK, I am still trying to figure out how LH and LX show status on the Boarding pass, and what it all means. I am Senator.

E.g. On my recent LH flights, I have the following remarks on the boarding pass:

On LH:
(1) M/M
(2) FCI
(3) API

On LX (over 2 days):
(1) FQTV LH-xxxxxxxxxx/SEN
(2) FQTV LH-xxxxxxxxxx
(3) FQTV LH-xxxxxxxxxx M/M
