The positioning of crews and indeed airframes does create big issues for the long haul carriers when it goes wrong for what ever reason. I had a similar discussion to yours with our Munich Office managers husband at our Christmas Party this December ,who works for LH in Munich in operations. The language issue with CC is something we tend to forget about as English speaker’s, as we to a degree get away with it as it is the world’s probably most used second language and obviously widely used in aviation. Others are not so lucky so having CC who can speak the language is essential.
