TAAG Angola Airlines is also a prominent addition to the list. Morbidly enough, a TAAG B737 crashed today in southern Congo - on the same day the EU put them on the blacklist.
Of further interest is the addition of six Bulgarian carriers to the list. Since Bulgaria is now a member of the EU, that pretty much means that these carriers are grounded. They can no longer operate within their home country, and I don't know how much business they can pick up on operations entirely outside the EU.
To be honest, most of the carriers on the list couldn't care less that they're on it (think "Equatoguineana de Aviación" or "Bellview Airlines (Sierra Leone) Ltd"), but for those Bulgarian operators, it's going to sting big time.
