BNA also has an elite security line - but only for the security checkpoint that services the A and B concourses. It is located to the far left of the A/B pier security queue and then merges in to the xray lines. They do accommodate all elite travelers and it is an easy walk from the A/B security checkpoints to AA's gates in the C concourse - just turn left after the security checkpoint. Can be a real lifesaver at busy times.
