AIRLINES BANNED from operating into the UK have now been listed by the Department of Transport. These are Star Air (Sierra Leone), Cameroon Airlines (Cameroon), Albanian Airlines (Albania), Central Air Express (Democratic Republic of Congo) and Air Universal (also of Sierra Leone). Any airline registered in Equitorial Guinea, Gambia, Liberia and Tajikstan is also denied British landing rights due to inadequate safety regulations by their home country.
