VASP


Viação Aérea São Paulo S/A (São Paulo Airways), better known as VASP was an airline with its head office in the VASP Building on the grounds of Congonhas-São Paulo Airport in São Paulo, Brazil. It had main bases at São Paulo's two major airports, Congonhas Airport (CGH) and Guarulhos International Airport (GRU). The airline was established on 4 November 1933 by the state government of São Paulo and started operations on November 12, 1933. VASP was the first airline to serve the

America and the United States. From 1994 onwards, Lloyd Aéreo Boliviano was encountering rising financial difficulties. As a consequence, the Bolivian government prepared the privatization of the airline and began to negotiate with potential buyers. On 19 October 1995, Brazilian airline VASP acquired 50 percent of the LAB shares. In an effort to cut costs, VASP aimed at a full merger of the two airlines, with a similar livery and a joint frequent flyer program as initial steps. In 2001, VASP sold its shares in LAB back to Bolivian

the country’s most important airports, Congonhas, located in the city of São Paulo, far from the coast. During its early years, Congonhas Airport was popularly known as "Campo da VASP" ("VASP's airfield"). In 1939, VASP bought Aerolloyd Iguassu, which included also a license to operate flights to the states of Paraná and Santa Catarina. In 1962, VASP became a national airline when it acquired Lóide Aéreo Nacional, and with it its license to operate nationwide. On 6 July 1959,

international routes. Until VASP's entry into the international market, Varig had, for all intents and purposes, been Brazil's sole international airline since 1965. However, after many years of mismanagement, financial losses, soaring debt and bad credit, in 2002 it cancelled all of its international operations to concentrate in the domestic market. By that time, VASP had plummeted from the second to the fourth position in the Brazilian airline market, flying an aging fleet of Boeing 737s (most of them of the obsolete −200 series)

and Airbus A300s. The company faced its worst crisis in 2004, which led to the suspension of service to many Brazilian cities and the cancellation of flights. As a result, VASP – once a proud, competitive airline – had its domestic market share reduced to 10%. On 27 January 2005, Brazil's then civil aviation regulator, DAC, grounded the airline from operating scheduled services pending a financial investigation. VASP was allowed to operate charter services until April 2005, giving it a chance to prove its financial stability in

American Eagle, the feeder carrier for American Airlines responded and began service on Sep. 5, 2007 with two daily flights to Dallas/Ft. Worth on 50-seat Embraer 145s. The service did so well that a third flight was added only seven months later. Mesa Airlines then ended all of their Roswell service on the last day of 2007 which left no flights to Albuquerque.

By 1996, short domestic and international services were restarted, with a livery that resembled VASP's. A single DC-10, also borrowed from VASP, allowed the airline to reintroduce services to Madrid's Barajas International Airport. Lan Chile owned 50 percent of the airline, wet-leasing two Boeing 767s to the company, but in 2004 sold its part to Lloyd Aéreo Boliviano. By early 2005 LAN had

The Brazilian airline VASP placed an order for ten Series 700s, with plans made for production in Brazil, while further orders for the 700 were placed by Swiss airline Globe Air and Taiwanese Far Eastern Air Transport, and production started on the new model. VASP cancelled its order, however, when it could not obtain financing from the Brazilian government, and Handley Page stopped work on the 700, scrapping six airframes on the production line.

It had been operating under the new Brazilian bankruptcy law since July 2006, and had its recovery plan approved on 27 August 2006. However, in 2008 it declared bankruptcy.

The crash of Flight 168 remains the third-highest death toll of any aviation accident in Brazil after Gol Transportes Aéreos Flight 1907 and TAM Airlines Flight 3054.

"Compañia Ecuatoriana de Aviación (CEA)" () was established in May 1957, after a group of American and Ecuadorian investors decided to set up an airline.

On December 22, 1947, Ruy Vacani founded the airline TCA – Transportes Carga Aérea S.A. in Anápolis, State of Goiás, Brazil, an airline specialized in transportation of cargo. Previously, in 1928, Vacani had also founded ETA - Empresa de Transporte Aéreo an airline that lasted for only for one year, being sold to NYRBA do Brasil.

Examples of such hubs are Turkish Airlines' Istanbul–Sabiha Gökçen hub, British Airways' hub at London-Gatwick, Air India's hub at Mumbai and Lufthansa's hub at Munich. By operating multiple hubs, airlines can expand their geographic reach. They can also better serve spoke–spoke markets, providing more itineraries with connections at different hubs. A given hub

Airline hub


Airline hubs or hub airports are used by one or more airlines to concentrate passenger traffic and flight operations at a given airport. They serve as transfer (or stop-over) points to get passengers to their final destination. It is part of the hub-and-spoke system. An airline operates flights from several non-hub (spoke) cities to the hub airport, and passengers traveling between spoke cities need to connect through the hub. This paradigm creates economies of scale that allow an airline to serve (via

The last MD-11 was retired from TAM's fleet in July 2009, which ended its use by Brazilian airlines (Varig, VASP, and TAM). In May 2007, Finnair announced the sale of their last two MD-11s to Aeroflot-Cargo to become part of the Russian airline cargo fleet in 2008 and 2009.

This is a common strategy among network airlines who fly only from limited number of airports and usually will make their customers change planes at one of their hubs if they want to get between two cities the airline doesn't fly directly between. Airlines have extended the hub-and-spoke model in various ways. One method is to create additional hubs on a regional basis, and to create major routes between the hubs. This reduces the need to

In 2001, Varig saw the birth of a new competitor in the Brazilian market: Gol Airlines and increasing competition of VASP and Transbrasil fighting for survival by dumping fares. Furthermore, for the first time since 1961, Varig lost the first place in the domestic market share in terms of passengers/km for TAM Airlines. Later in the year, the September 11 attacks further

Allegiant Air, JetBlue and Southwest Airlines are examples of US-based airlines that consider some of their focus cities run like a hub. The hub-and-spoke system allows an airline to serve fewer routes, so fewer aircraft are needed. The system also increases passenger loads; a flight from a hub to a spoke carries not just passengers originating at the hub, but also passengers

Initially two 3-passenger Klemm Kl 31A were bought and on July 20, 1933, flights between Curitiba and São Paulo started.

Under the Brazilian government's neoliberal policies newly introduced at the time, VASP was privatized in 1990. A majority stake was bought by the VOE/Canhedo Group, a company formed by the Canhedo Group of Brasília and VASP employees.

Additionally, airlines can come to monopolise their hubs (fortress hubs), allowing them to freely increase fares as passengers have no alternative. Airlines may operate banks of flights at their hubs, in which several flights arrive and depart within short periods of time. The banks may be known as "peaks" of activity at the hubs and the non-banks as "valleys". Banking allows for short connection times for passengers. However, an airline

deregulated in 1978, several other airlines adopted Delta's hub and spoke paradigm. Airlines have extended the hub-and-spoke model in various ways. One method is to create additional hubs on a regional basis and to create major routes between them. That reduces the need to travel long distances between nodes near one another. Another method is to use focus cities to implement point-to-point service for high-traffic routes and to bypass the hub entirely. The spoke-hub model is applicable to other forms of
