After rolling out its corner-stone strategy throughout the rest of its domestic network, American rounded out its service expansions and terminal upgrades by announcing 10 new destinations for its Los Angeles hub, from 05-Apr-2011. American estimates that its expanded service will add approximately USD600 million a year in local economic impact, increasing its total annual economic impact in Los Angeles to approximately USD6 billion. However, it did not quantify what the new service would do for the airline itself. American expects to add to its current 4,400 employee complement with the expansion.
