If you're going to do it you may as well get the respirator. They are cheap. Surgical masks seem kind of useless for incoming particles (good for outgoing though).
It does seem like overkill at this point though. The fact that there is one case in Seattle and one in Chicago tells me that it's not too likely to transmit it on a plane (otherwise there would be a lot more then one in each of those cities... a whole planeful of people for not catch it)
