The San Diego County Regional Airport Authority is donating free digital advertising space at Lindbergh Field to the San Diego County Water Authority. The advertising is valued at tens of thousands of dollars. Starting the day before Thanksgiving, monitors at the airport’s baggage claim carousels in both Terminal 1 and 2 began announcing that San Diego is “Brought to You By Water.” The Water Authority said the ads’ takeaway message is the importance of water reliability to the region’s core industries, including tourism, manufacturing, agriculture and brewing.
