KL joining OneHeathroWorld just doesnt seem to make sense.... NW has obviously cast its lot for SkyTeam by joining with DL (no way they're going to, or be allowed to, break that for AA) and KL is hopelessly tied to NW.
KL would either have to spend a sh!t-load on breaking up with a stable/proven partner such as NW... to risk an unproven relationship with a historically-instable alliance partner in BA; or join AF.
