U.S. Airways is way late in this China game. Getting another sub-fleet just to accomodate this PHL-PEK is going to be a very expensive venture and quite risky. The competetion is also firing up as everyone got a piece of the cake this time around. It would directly compete with Continental's China presense to PEK, and HKG and soon to include PVG out of EWR. They have been doing it for years. I would give it a 50/50 chance right now.
