The story
Cairo Aviation is a charter company operating Tupolev Tu-204-120 passenger aircraft and Tu-204-120C all-cargo aircraft on a dry lease basis from Sirocco Aerospace International.
Beside domestic routes in Egypt, the company mainly operated on international routes to various destinations in Europe, Africa and the Middle East. Furthermore, Cairo Aviation operated scheduled flights for the national carrier Egypt Air on many occasions.
Being a sister company to Sirocco Aerospace international, Cairo Aviation was a test vehicle for the Tu-204-120 aircraft when it first entered service. Sirocco was testing many aspects of projected- versus actual operating costs; dispatch reliability; noise and emissions levels; and component wear and tear among many other things. Satisfied with the results, Sirocco began aggressive sales and marketing efforts for its aircraft.
