well lets safely assume gareth works at the airport, and that he has it all in control.
I'm sure all airports could do more to advertise but then again BLK will never be in a position to aggressively market in the same way LPL does. Same goes for BOH v SOU.
The airlines at Regional airports know this and they have to advertise more heavily than normal, unless they feel bookings are going VERY well in which case minimal advertising is necessary.
