LAN Offers Low Fares on Connecting Flights in South America LAN Airlines and its affiliate TAM Airlines are putting South America on sale in North America. Through Aug. 5, travelers booking LAN and TAM flights from the United States to Bogotá, Buenos Aires, Lima or Santiago can get connecting flights to leisure destinations like Salta in Argentina, Cartagena in Colombia, Iquitos in the Peruvian Amazon or Punta Arenas in Chilean Patagonia for $13 to $27 round trip. Outgoing flights from New York start at $949 round trip for Buenos Aires, $899 for Santiago and $799 for Lima. Prices are similar from other airports including Los Angeles and San Francisco. Bogotá-bound flights originate in Miami from $249. Both international and domestic connecting fights must be booked together either via the Web sites or by calling (866) 435-9526. The deal represents a significant saving over à la carte pricing; a recent Web search for mid-August flights departing from Buenos Aires to Bariloche, Argentina, started at $582. The offer is good for travel between Aug. 15 and Dec. 5, in time for late-winter skiing in the Andes or early-spring hikes in Patagonia.
