Well the 747s are coming to the rescue this week with ZNG out (I heard it was hit by a VA catering truck - not sure if it true). So running the 8 aircraft with no pad in the schedule will come back to cost you when you don't have a spare.
The 747 will operate the MELHKg run on Saturday and also doing MELSFO in the coming days. The 330s are also having significant issues.
The 747 wont be around to save the day forever......
