Based on my experience with Lufthansa. That's an organization that should fail. If anything happens on your journey that is not average, the agents always blame you first.
So basically every airline ever? Unless you are in the ultra premium VIP exclusive membership club.
I hold SU and TK gold elite, both just emailed me: Due to the crisis the both extend my gold elite status for 12 months/6 months without any need to accumulate miles to reach status.
Just one of the many examples about how LH has treated me badly:
LH has to downgrade the plane from FRA-LHR, and people will get involuntarily denied. (LH Metal FRA-LHR, UA Metal LHR-ORD) I have 2 award tickets on my iterary. I offered to voluntarily reroute we can go United metal leaving Germany, the agent's response was "WHO TOLD YOU THIS!" They tried to offer both of us FRA->ORD direct via LH, I rejected. They ended up sending my bag to JFR later for me to claim missing baggage. (United had to fix their problem) My dad's bag arrived just fine in ORD.
