Avianca El Salvador, formerly Transportes Aereos del Continente Americano, simply known as TACA Airlines, is an airline owned by the Synergy Group based in El Salvador. As TACA, it was the flag carrier of El Salvador. As Avianca El Salvador, it is one of the seven nationally branded airlines (Avianca Ecuador, Avianca Honduras, etc.) in the Avianca Holdings group of Latin American airlines. This Airline has been in operation for 75 years.

TACA owned and operated five other airlines in Central America, and its name was originally an acronym meaning Transportes Aéreos Centroamericanos (Central American Air Transport), but this was changed to Transportes Aéreos del Continente Americano (Air Transport of the American Continent), reflecting its expansion to North, Central, South America and the Caribbean.

On October 7, 2009, it was announced that TACA would merge with Avianca, though TACA maintained its name until the merger was officially completed on May 21, 2013.

TACA Airlines was the second-oldest continuously operating airline brand in Central America and the Caribbean after Cubana de Aviación.

The airlines that made up TACA Airlines were:

The airline's hubs before Avianca merger were:

TACA was founded in 1931 in Honduras by New Zealander Lowell Yerex. TACA began operations with a single-engine Stinson plane. Since its beginnings, routes covered all the national territory and its aircraft sported the XH Mexican registration (which were changed later by HR). The idea of its founder was to establish one airline in each Latin-American country, such as Aerovias Brasil in Brazil and other TACAs in Mexico, Venezuela, and Colombia.Out of all the TACA franchise airlines created, only TACA International of El Salvador survived,

As a consequence, in 1945 Yerex left the company and TACA moved its headquarters to the Republic of El Salvador where it was modernized and expanded, the company then established investment groups in other Latin American countries to be sold to domestic airlines, which in the case of Honduras TACA was sold to SAHSA. Later TACA was organized as an international company having its headquarters in San Salvador only under the name of TACA International Airlines.
