EcoJet (8J, Cochabamba) is poised to start operations in late May following the recent arrival of its first aircraft, an ex-FlairJet (Germany) (Nuremberg) ARJ-85 D-AVRK (c/n 278) on April 23. The airline's initial network will cover all of Bolivia's major cities. EcoJet will compete with fellow new-comer Aerolinea Boliviana AeroStar (Santa Cruz Viru Viru) and veteran carriers, Amaszonas (Z8, La Paz El Alto) and BoA - Boliviana de Aviación (OB, La Paz El Alto), both of whom have announced plans to upgrade their fleets with CRJ200s and B737NGs during the second half of the year in preparation for the added market pressure. Not to be outdone, Transporte Aéreo Militar - TAM (La Paz El Alto), the Bolivian Air Force's carrier, is also expected to take delivery of a first B737-300 in the near future.
