TEGUCIGALPA, Honduras–Regional Honduran Airline AEROLINEAS SOSA is expanding its network to neighboring Guatemala operating its only jet, a Bombardier CRJ-100. The airline operates mainly as a domestic airline in Honduras, serving Tegucigalpa, Sam Pedro-Sula, La Ceiba, Brus Laguna, Puerto Lempira, the Bay Islands (Roatan, Utila and Guanaja) and their only international flight to George Town in Grand Cayman. Their fleet is composed of 4 LET L-410 UVP, 2 BAe Jetstream 31s, 2 Saab 340 and 1 Britten-Norman Islander. The airline sports a blue and white livery and the Honduran flag on the tail, as one time now defunct flag carriers TAN and SAHSA used to have. In all Central America the existing small airlines are expanding its route structures (Air Panama, TAG of Guatemala and now Aerolineas Sosa) and in other countries start-ups (El Salvador, Costa Rica and Nicaragua) could be partly after Avianca’s take-over of Central American airline TACA.
