Going back to where it looks like DEPs started joining long haul fleets about a year ago, I count:
310 onto the 320 at Heathrow
60 onto the 777
24 onto the 350
13 onto the 787
1 onto the 380
A total of just over 400 courses.
Given the numbers involved, I am more inclined to believe it is down to training capacity.
