I disagree that Detroit has never been an important city for AA. At the time of deregulation, AA flew nonstop from Detroit to BUF, SYR, ORD, BOS, LGA, EWR, STL, IND, SFO, LAX, DFW and PHX. Of course, as Republic grew in Detroit, AA moved its focus to ORD and DFW. Things are grim right now for the city of Detroit, but it's still a huge metro area that, although it's not growing, will take a long time to wither away. With consolidation, and the new 2-class 76-seaters, new AA should be able to serve DTW nonstop from ORD, DFW, LGA, JFK, PHL, CLT, DCA, PHX and MIA. That should be enough for a club even if AA or US separately could not justify one.
