Thanks, but I guess I should have been more specific with my question. You can fly an augmented flght over 8 hours with a Class 3. Delta currently uses Class 2 & 3 for their 8-12 hour fights on 330-300/767/757. The longer range 744/777/330-200 have Class 1. The latest agreement calls for Delta to convert all the A330s to Class 1 regardless of range.

I was wondering what the other international carriers were using.
