I think that those in MSP, ATL, and DTW won't notice much difference, and what they see might be positive. I would think MEM and CVG might see pretty significant cuts. JFK will continue to push up against capacity, so little change there.

A lot of smaller markets will likely feel a big pinch.

What I am personally curious about would be:

1) What happens with BOS? Does it see some scaling back? Or does DL/NW make a play at being the biggest fish there? And can they kick CO out of Terminal A?

2) What will the international model look like? A lot of DL's recent growth has been point-to-point. NW, on the other hand leverages the heck out of AMS and NRT? Will we see JFK-everywhere or everywhere-CDG/AMS?
