It's important to note that the comparative ease of the DAL/NWA integration is due in large part to the relative similarity in their demographics.
Both are large major airlines. (Real airlines, if you will.) They are close to the same size. They both have extensive international routes, and both have a large number of wide-body airplanes.
And both companies began operations within three years of each other, in the 1920's.
The only notable demographic difference is that the DAL pilot list is somewhat younger, owing to the large number of early retirements prior to the bankruptcy and merger. However, one could argue that the DAL pilots have already benefited from their own attrition, in that they were most likely slotted on the combined list with regard to the positions they gained from it.
The new US Airways, in comparison, is a hodge-podge of regional airlines, with only one side of the most recent merger having only a handful of wide-bodies. The oldest of the melange of airlines started operating in 1939, and the youngest of the mix in 1983. And the larger, and demographically older side experienced the worst stagnation in the history of any surviving airline. (Which is hardly the fault of the other side.)
The point is, most USA pilots would probably gladly trade their situation for that of the NWA/DAL pilots.
Of course, that does not mean that you won't hear any DAL or NWA pilots howling on a hotel van or in a food court about how badly they got screwed.
