Good question Lee M! This next few months will see all of this addressed, but I do worry about what the UAL CBA Terms & Conditions will give up. The European flying at UA is 100% 767 with a first class bed for the crew rest facility in BOTH directions. CAL is a two class operation from what I can tell, with #3 only used on Westbounds over 8. No disrespect, but I can see "min fuel" and a poorly rested crew on the Westbounds from EUR into IAD. They had a chronic min fuel situation going into EWR according to their safety committee, why so would IAD arrivals be any better.
Watching with interest. R
