Well, looks like -once again- there are two sides to every coin. Whether pax or freight, too short or too long layovers, we all just fly too much these days and have way too little time to rest at home.
I hear that Cargolux has apparently lost quite an unusual number of (relatively young) pilots due to medical reasons in the last few months. I don't know the details, though.
Happy landings
