En airliners.net hay unas fotos muy bonitas de unos Embraer 145 de EGA, pero no sé qué rutas han volado estos aviones, si es que lo han hecho alguna vez.
Madrid is one of the few European airports with air links to Malabo, capital of Equatorial Guinea, a former Spanish colony. There is always high demand on this route, which was for many years flown by Iberia only. In the late 90's Ecuato Guineana de Aviación started as a Guinean joint stock company in order to claim the Guinean flight rights between the two countries; actually, the flights were operated by Spanair airbus planes, and IIRC they were a codeshare because for some time Spanair was selling their tickets to Malabo on their own.
There are some very nice pictures of some EGA Embraer 145 planes at airliners.net, but I don't know which routes have been flown by these planes, if any.

This last ad is from 2005. The airline had changed its name to Euroguineana de Aviación by then.
