With the introduction of the Multi-Crew Licence with respect to crew trained specifically for a particular airline's operations the amount of hours in the air is likely to get less rather than more.
I'm largely an uninformed outsider, but I am still out on this concept. Increaced automation does take a large chunk of human error out of the practice of flying people through the sky but it introduces a whole set of new different error traps and it would seem obvious that training and currency need to be approached differently than they were in the past.
