Boliviana de Aviacion (BoA) and other carriers have quickly absorbed the traffic of bankrupt Aerosur since its shut down in April 2012, according to traffic figures published by the Bolivian civil aviation authority (DGAC).
During the first three quarters of 2012, domestic passenger traffic was 1 million passengers, down from 1.08 million during the same period of 2011, when Aerosur's market share still exceeded 45%.
State-owned BoA benefitted in the most from Aerosur's disappearance, as its passenger traffic increased by 58%, boosting its market share to 83% of the domestic market.
Regional carriers Aerocon more than doubled its market share from 5% to 11% while Amaszonas tripled its presence to 6% in the first nine months of 2012.
While the data does not provide specific capacity and load factor numbers, the DGAC says that the "available seat capacity decreased much more than the traffic" and acknowledges that Bolivia still shows "higher than usual load factors", which "makes it sometimes difficult to get a domestic air ticket on short notice".
In addition to the domestic operations, BoA has started international flights on routes previously operated by Aerosur, including to Buenos Aires, Madrid and Sao Paulo.
