To take a page from CL65's book... isn't it going to be a ding to Star Alliance on the East Coast to lose USAirways?

Would it then make some sense for UAL to pick up B6 to have a ton of JFK feed they don't have, mostly to connect to their Star Alliance International partners?

I am not sure of their presence at LGA, but it seems that UAL is serves their NYC customers fairly well from EWR. So why not JFK to get the International connections from their Star Alliance customers and the local Long Island traffic?

Besides, UAL will be at a disadvantage compared to the other "big three" on the east coast after AA and USAir merge. B6 would bring a lot of east coast traffic (BOS and JFK) they don't have.
