I wouldn’t flippantly call a whole group of Jews “reshaim”, they might be tinok shenishba or somewhere in between. Rasha is a very strong term (which should only be used by The Wolf in reference to himself).
I heard from a “3rd party” quoting the Business Halacha institute that since El Al is run by non-frum Jews there is less of an issue of Ta’us Yisroel. V’tzarich iyun.
