“We are looking at the 787-9 to replace some 747-400s and also examining what improvements Boeing will offer on the 777 with 787 technology,” Joyce said. “If there is considerable 787 technology in the 777 it could be outstanding.”
Isn't that precisely what was said when an ER 777 (772ER?) was being considered for direct PER-LHR?
So what has changed?
