That's true, but what about the suspended mist of droplets left in the air after a sneeze? You walk through that on your way back to the lavatory and it contacts your eyeballs- Ebola loves eyeballs as an entry route. Or somebody infected has just been sneezing in the bathroom, and you're the next one in? Strictly speaking, that isn't airborne transmission, but you haven't touched the bodily fluids of an infector that you're aware of.
Just curious, it would seem that it would be a hazard in a close environment like a commercial flight.
That said, I agree that is unlikely to be Ebola, with such a rapid manifestation of symptoms. No, I’m not a doctor. :-)
