Made several trips with my MBA, only response was a "Cool" from the screener at Eagle County airport in Colorado. Screeners in Tucson and Washington, DC were either familiar with it or didn't pay attention.
I've been traveling with an air since just after its release and have probably taken 60 - 70 flights with it since, all without a single problem going through TSA.
There is no such thing as intelligence and common sense when it comes to the TSA.
There, that's better.
