According to the latest 'Open Skies' issue, TC says in black and white that we will carry 70m passengers by 2020. That compares with our current annual of 39m. It's almost double.
Granted aircraft size will increase but so will the numbers of pilots needed as the 380 takes on additional US ULR.
Interestingly he also confirms the 70 A350s in the same lead-in article.
Finally, word is that the 777F is chewing up crews with these new Latin routes (Mex City & Quito)
I think our FOs will be fine with upgrade timing, long may it continue.
