According to an artice in today's New York Times (http://www.nytimes.com/2009/09/01/bu...bal/01air.html), the code shares are only available to 12 American cities. That's nothing, I would expect this to have little, if any, effect on CO.

Plus, with LH flying into both JFK and EWR, they want the connections for their pax from both NYC airports. I don't think one should reasonably expect just because CO will be in *, that all international * carriers would drop service to JFK, and go excusively to EWR. CO may wish that and AC has done this already but it was a while ago, and I'm not sure that was all, or even mostly about CO connections, but more about cost considerations since it only had 2 daily JFK flights and was contracting UA out for all ground ops, but could put those flights into its EWR ops). It doesn't make sense for the international carriers, who need a JFK presence too.
