TAM Airlines is the largest airline in Latin America in terms of number of annual passengers flown.Along the first countries to have regular airlines in Latin America were Colombia with Avianca, Chile with LAN Chile (today LAN Airlines), Dominican Republic with Air Dominicana, Mexico with Mexicana de Aviación, Brazil with Varig, and TACA as a brand of several airlines of Central American countries (Honduras, El Salvador, Costa Rica, Guatemala and Nicaragua). All the previous airlines started regular operations before World War II.
The air travel market has evolved rapidly over recent years in Latin America. Some industry estimations over 2000 new aircraft will begin service over the next five years in this region.
These airlines serve domestic flights within their countries, as well as connections within Latin America and also overseas flights to North America, Europe, Australia, Africa and Asia.
Just one airline, LAN (Latin American Networks) has international subsidiaries: Chile as the central operation along with Peru, Ecuador, Argentina and some operations in the Dominican Republic.
The main hubs in Latin America are Sao Paulo and Rio de Janeiro in Brazil, Bogota in Colombia, Caracas in Venezuela, Guayaquil in Ecuador, Lima in Peru, Mexico City in Mexico, Panama City in Panama, Buenos Aires in Argentina, Santiago in Chile and Santo Domingo in the Dominican Republic.
 Regulatory considerations
Pakistan International Airlines Boeing 747-300. The Government of Pakistan is the majority stake-holder in the country's flag carrier.Many countries have national airlines that the government owns and operates. Fully private airlines are subject to a great deal of government regulation for economic, political, and safety concerns. For instance, governments often intervene to halt airline labor actions in order to protect the free flow of people, communications, and goods between different regions without compromising safety.
The United States, Australia, and to a lesser extent Brazil, Mexico, the United Kingdom and Japan have "deregulated" their airlines. In the past, these governments dictated airfares, route networks, and other operational requirements for each airline. Since deregulation, airlines have been largely free to negotiate their own operating arrangements with different airports, enter and exit routes easily, and to levy airfares and supply flights according to market demand.
The entry barriers for new airlines are lower in a deregulated market, and so the U.S. has seen hundreds of airlines start up (sometimes for only a brief operating period). This has produced far greater competition than before deregulation in most markets, and average fares tend to drop 20% or more. The added competition, together with pricing freedom, means that new entrants often take market share with highly reduced rates that, to a limited degree, full service airlines must match. This is a major constraint on profitability for established carriers, which tend to have a higher cost base.
As a result, profitability in a deregulated market is uneven for most airlines. These forces have caused some major airlines to go out of business, in addition to most of the poorly established new entrants.
Singapore Airlines Airbus A380 lands at Changi Airport. The Singapore Airlines was the first international airline to operate the A380, the world's largest passenger airliner.Groups such as the International Civil Aviation Organization establish worldwide standards for safety and other vital concerns. Most international air traffic is regulated by bilateral agreements between countries, which designate specific carriers to operate on specific routes. The model of such an agreement was the Bermuda Agreement between the US and UK following World War II, which designated airports to be used for transatlantic flights and gave each...
