@Juventus: The version we have over here is a bit different. Both Airbus and Boeing were heavily competing for this deal, however the CIA
/NSA fished every fax from Airbus to Boeing. Boeing was told the prices Airbus was offering and in this case was always able to be a tad lower than Airbus´ offer.
had 10 A330-300 and 10 A340-300 on order, later changed ot to 13/7 (?) before completely cancelling it.
had 5 A340-300s in the books for years, but at one point decided to cancel it. No idea why they ordered them in first place.
apparently has an interesting deal with Airbus: the old order stayed in the book and after every delivery of an 330-200/300 of the new order, one frame is canceled of the old order. Suppose it has to do with the old framework and probably the deposits paid for the old order. However, as of today NW
already has more A330-200/300 on order than the old order ever had.
