This is the key point, which you unfortunately don't clarify.
Is it really "a couple" as in two? Then the airline was totally wrong.
Or was it a majority of the group? In which case, the airline might have been right.
Unfortunately, your article is very short on details and very long on bias.
I might add that I am in no way sympathetic to Lufthansa or really any airline at all. They might well be wrong - they often are. There's simply no way to tell either way from this uninformative and rabble-rousing article.
No claps. Next time, put some real information in.
