Select one of the South America airlines that get you where you need to go

Evaluate where you and your staff travel to the most, and then see which of the South America airline carriers has the most flights to and from these destinations. Explore international as well as domestic carriers.

I recommend: Aerolineas Argentinas provides commercial transportation throughout Argentina. Gol Intelligent Airlines is based in Brazil and has a growing international and domestic network.

Compare the frequent-flyer programs of several South American air carriers

From free trips to rewards at hotels and restaurants, frequent-flyer programs are a benefit that shouldn't be overlooked when choosing among South American airline carriers.

I recommend: TACA’s DISTANCIA program has partnered with United Airlines, Iberia and Avianca to provide frequent travelers on this South American airline with travel rewards. Copa Airline’s OnePass program allows travelers to use reward miles toward trips to 500 destinations. What’s more, the miles earned never expire.

Seek out one of the South American air carriers that offer special privileges for business travelers

Frequent-flyer programs are great, but they have become a bit rote. Many of the South American airline companies take customer service one step further with "perk" programs just for frequent business travelers.

I recommend: LAN Airlines offers three types of service levels for business travelers—Business Class, Premium Business and Business Express Class—not to mention top-notch First Class service. Avianca’s Preferencia program has benefits specially designed for business travelers, including direct discounts on travel purchases.
