Korean Air was looking to increase its campaign reach in the region in conjunction with the newly launched local language websites for Indonesia, Thailand and Vietnam. Simultaneously, Korean Air was seeking to achieve performance benchmark that is beyond its past campaigns.


Several strategies were identified and implemented to achieve the KPI, including household extension, look alike modelling & retargeting. Additionally, dynamic creatives based on target country and local language creatives in Bahasa Indonesia, Thai and Vietnamese were created to promote newly launched local language sites.

Household extension

By leveraging on Knorex XPO, a proprietary full-stack advertising platform with several key advertising technology components, Knorex worked closely with Korean Air to execute the campaign into global ad exchanges to programmatically target the appropriate channels and audience segments. Using household extension, Knorex not just targeted individuals looking to buy air tickets for leisure, but also the influencers within the household. This carefully crafted strategy ensured that relevant and highly engaging ads were shown to all the stakeholders in making decision.
