Smart move, because it will allow them to be more profitable in Europe. The 777s can still be sent to the premium markets...Tokyo, Buenos Aires, Sao Paulo, Santiago de Chile, London, Paris, Frankfurt, and Madrid (hopefully MAD will go to a 777 finally)...while the secondary markets can get the 763s. This not only allows for better aircraft utilization, but also allows for more oppurtunities for expansion in Europe and deep South America to markets that would otherwise not be able to support the current 763 configuration. For example, Asuncion (which AA does serve, but via GRU), Barcelona, and Birmingham (it is said that one of the major reasons AA is pulling out of Birmingham this October is because of they way thier 763s are configured). Unfortunatley, it means no more business-class seats for coach prices on select 767-operated flights, and that AA's first class service, which no other American carrier can match, will only be available domesticly on four flights (AA69, MIA-DFW; AA906, MIA-LAX; AA999, LAX-MIA; AA943, DFW-MIA).
