The A330-200 has a range of 6400nm at max weight. Perhaps those A330-200 orders could be sped up if it's longer range that US seeks. Parker might be right in saying that none of the aircraft have the range for those longer trips once you factor in the things like seasonal winds, specific configuration (seats, weight, fuel, cargo, etc.). The numbers given on Airbus' site are best case scenarios and don't take into consideration options and configurations each airline chooses.
