The idea got cememted once Delta came out with "Economy Comfort" for their International equipment..
I thought it was kind of Up in the air before that.. Now We'll see if we keep the 3 class interiors for the International fleet.
Competing against the likes of Singapore, Asiana, All Nippon, Lufthansa, British, Emirates and the like We'll not ONLY need to fly a superior product in our cabin Equipment but Keep 747's for the Extreme long Hauls as long as we're competing againse the A380. IMHO
