BNA has the same silly self policing "who gets in what line" policy, as does DEN. The kettles don't see the signs and there's nobody there to help them read. Granted the volume out of BNA is nowhere near MCO, but still, it's a stupid system if people don't play nice.

In DEN in addition to the Clear lane (which is back there also) they have a lane for all carriers elite and F pax with someone checking the BPs, so the kettle population isn't hindering progress.
