Google News forwarded me this article yesterday and I thought it was a good analysis of Delta's strengths and weaknesses with growth into China. They didn't come right out and say it, but it eludes to our long haul market being stymied by the lack of an aircraft with the ability to serve the longer thin legs that would work for China's large secondary cities. Don't worry, our code share/jv partners will get those type of aircraft before us and they can just do all the flying.
