According to this thread on Airliners.net, American Airlines has changed their minds a bit about the seating configuration in their new 777-200s.
Originally, the aircraft were to feature 45 business class seats, 39 Main Cabin Extra seats, and the remaining seats in coach.
Instead, they will reduce the number of business class seats down to 37 (36 for sale, with 1 crew rest seat), 36 Main Cabin Extra seats, and the remaining seats in coach.
The headline here is that there will be 9 fewer business class seats available, which means there won’t be quite the award availability you may have hoped on the new planes.
