Tourism Ireland is collaborating with Iberia Express to promote Madrid-Cork flights, and bring more Spanish visitors to Cork and the South of Ireland.
Channels used include out-of-home - electronic billboards, and billboards in transit stations - as well as radio, online, e-mail and social media.
Ireland saw 443K visitors from Spain in 2017.
Tourism Ireland has its work cut out for it in trying to offset Brexit-related weakness of its #1 British market. Best of luck.
