National flights are available, but not all that common in Bolivia, so getting around by plane is fairly expensive. There are major airports in Bolivia, Sucre, Santa Cruz and Cochabamba, and it is likely you will be flying into or out of one of these destinations. One of the most touristed flight is the La Paz to Ruennabaque route, as by bus this is an 18+ hour trip on horrible roads, many of which are nearly unusable during the wet season. Local airlines include: Aerosur (www.aerosur.com), Amaszonas (www.amaszonas.com), Aercon (www.aerocon.bo), TAM (the military airline, serves many cities around the country), Aerolineas Suramericanas and the new government airline BOA (www.boa.bo). These airlines have offices in most of the major cities, and flights can also be purchased through various tour agencies.
