This idea didn't come from marketing. It was proposed by Jamie Durnin, an Aer Lingus cabin manager.

Starting October 25, Aer Lingus's Dublin-to-Nashville service will fly as EI95, a nod to "9 to 5." The return flight to Dublin becomes EI92. On approach to Nashville, the crew will identify themselves to air traffic control as "Shamrock 925."
