^ I have NEVER stated it would be done for International (Global) flights.
The scenario I see is what HSLD pointed out.

CALFO , you state this is "a non issue".
Our job (and the Union's too..) is too see if there are scenarios that hurt us.
A crew is scheduled to fly EWR-LAX, sit for 1:30 and then do LAX-PHX. Flight time 8:30. Sit in LA about 1:30 (there are things that also happen with regards to crew meals at the 1:30 mark).
If this gets delayed.. the crew is still legal for a while. But if not, due to some sort of weather issue.. say "SWAP" is in effect.. certain rules get thrown out!
The crew could get re-assigned.. (as I see) and that could effect their end time and also their "pay".

Not to mention, 9 hour un augmented is manpower negative.
