Pretty interesting development, I mean DEC's are not exactly unheard of, as a matter of fact DEC's are the norm in many parts of the world but in the biggest market that produces pilots, to start to see DEC's into widebody operations is very significant.
What is even more interesting is that the majors don't seem too worried about the pilot supply since they haven't done very much into investing in pilot production.
Will we ever see DEC's at major carriers? A few years ago "never" would have been the answer, now I'm not so sure that we can say that it will never happen!
