A marketing name is different from a corporate name. US, with 7 or more regional partners, markets all their flights as US Express but each has it's own corporate name. Someone said that Eagle now applied to all AA regional flights and that the old American Connection reference to contract regional partners had been dropped. No problem since it's just the marketing. Likewise I see no reason why AA would have to change the Eagle marketing name to match each of the regional partner's corporate names.
