Yawning is NOT contagious. The reason it seems like that is because the people around you are in the same environment that you are and you yawn to cool down your brain. That is why it seems contagious.
Actually it is contagious, because when you see a person yawning, it triggers an empathetic reaction, causing you to yawn.
