ContinentalEWR is right. The biggest cuts will be in San Jose and Austin, and Raleigh-Durham fits the profile of those two cities as well, although I do not think Raleigh will see big cuts.
Apparently, there will be a major increasing in flying to Mexico from all thier hubs, including many new routes (such as already announced ORD-PVR and BOS-CUN; and MIA-CZM is rumoured to be coming, among others).
Also, lot's of extra Caribbean flying from MIA, JFK, and BOS. Some frequency cuts on MIA-Central America (nothing major; MIA-GUA/MGA/SAL/PTY are each loosing only two weekly frequencies) and capacity cuts to South America (but not frequency; like DFW-CCS and two MIA-CCS flights down to a 738 [Colombia and Ecuador are healthy, however]). Though they may be entering two new markets by the end of 2003, those being Valencia, Venezuela (that totally depends on if or not Venezuela's economy and traffic recovers) and Liberia, Costa Rica.
Leisure routes are key this winter, as evidenced by BOS-LAS, MIA-LAS, and LAX-EGE.
St. Louis will suffer in terms of capacity, because rumours are they are going to be making STL something like 45% RJs.
New European routes too, like JFK-FCO and JFK-BCN. Hopefully that will not be all.
In the end, MIA and JFK will likely see the bulk of the benefits; SJC and AUS will suffer the most, as mentioned. ORD and DFW probably won't feel the route changes that hard, and neither will STL, but STL will see a lot of RJs (like on STL-IAH and STL-CLT, the two most recent all-RJ switches).
