Perhaps the folks at ILM need to chat with the folks at the Columbus Airport in Georgia, which also has scheduled air carrier service. During the show there, the Air Boss was aware of the airline schedule, got an inbound/outbound call from ATC, and suspended the airshow until the scheduled airliner landed/departed (this was even built into the behind-the-scenes flow schedule). TOTALLY transparent to the airline customers. The announcer played it up really well & kept the crowd entertained until the air show portion started again when the airliner was noo longer a factor. No brainer if you ask me.
