There has actually been a case of an Ebola-carrier travelling by plane to Johannesburg, back during the Gabon outbreak in 1996. The only other person he infected was a nurse who had come into direct contact with some of his blood. She died a short while later, but infected nobody else.

Ebola is a frighteningly deadly virus, so this sort of research is very encouraging, but its lack of an aerosol delivery mechanism and its quick mortality cycle both mean that it will likely never cause an epidemic on the scale of Bubonic Plague.
