 :: To reinforce what  has posted above.  The leased 77W MSN 35298 C-FITW from ILFC is delivered and in service.  See  .  As to the mix of 77W and 77L, your guess is as good as mine.  I believe the contract allowed AC to vary the aircraft mix, so the Boeing numbers may, in fact, be correct - i.e. 8 and 8.  I doubt that we will see updated numbers respecting the mix from AC anytime soon.  Regards
