I believe the question was about Latin America, not only South America. NW does serve Latin America. They serve MEX, MBJ, SJU, and have seasonal service to ACA, CUN, PVR, and GCM. Their is no need for them to undergo any rapid expansion throughout the rest of the region, because they can route their passengers through IAH or EWR with CO. They are better served concentrating on Asia and to a lesser extent Europe, especially Amsterdam. NW has specialized in the art of codesharing and reciprocal benefits. Their arrangement with KLM was groundbreaking, and still highly regarded as the most beneficial agreement in the industry. The pact they have with CO is also highly beneficial, especially in regards to Latin America. Why should they deploy assets better used elsewhere when there is no need?
