El Alto once have served as La Paz airport and railway service workers' living area. Now it's a big city with a population larger than La Paz. Altitude of the city is about 4,058 m (13,313 ft) above sea level. El Alto is mostly inhabited by Aimara people.
The city of El Alto is spread over a broad area to the west of the canyon of La Paz, on the altiplano. The buildings are low - a limitation imposed by the airport.
Life conditions on altiplano are less friendly than these down in La Paz. People in El Alto are poorer and feel discriminated by people in La Paz. However, government invests in education there, which may bring a positive change.
El Alto International Airport (IATA: LPB) (ICAO: SLLP), El Alto. This is the world's highest international airport; at 13,313 ft/4,058 m above sea level, it's almost half as high as a jetliner's cruising altitude, and takeoffs require a longer runway due to the thin air. There is an airport departure tax of US$25 for international flights, Bs15 for domestic flights. Tax can only be paid in cash, but several ATMs which also give out US$ are availbale at the airport.
Most South American airlines (LAN, TACA, Avianca, SkyAirline etc.) serve El Alto Airport as well local airlines (Boliviana de Aviación (BoA), Transporte Aéreo Militar (TAM), Aerocon and Amaszonas). Most international flights will make a stop over in Santa Cruz to pick up or drop off passengers. American Airlines is currently the only U.S. carrier serving Bolivia, with one daily flight from Miami.
State-funded BoA and TAM (usually for a cheaper price) serve major domestic destinations as well as some major South American hubs. Aerocon mainly provides air links to communities in the Beni Department via their hub Trinidad. Amaszonas provides direct service to tourist destinations like Rurrenabaque or Uyuni. LAB (Lloyd Aéreo Boliviano) was Bolivia's national airline until April 2007, when services were suspended by the Bolivian government due to financial problems. Another private operator, Aerosur, has also now ceased operations, due to a dispute with the Government over unpaid taxes.
