I am worried about getting sars when i travel from china on a plane, any precautions?

Wear a good mask: S(Severe) A(Acute) R(Respiratory S(Syndrome) started in Hong Kong and is a coronavirus. Try not to sit near someone who is coughing a lot and use a mask if available.

Unclear: Studies show that seated passengers are at a lower risk of exposure than those who move around a lot. On the other hand, its not clear that coming across SARS in China is necessarily less problematic than leaving China on a plane. Avoiding holiday travel in China also seems like an effective strategy.
