Southeast Asian travellers are habitually loyal to their national carriers. Based on the Japanese concept of “ichi-go ichi-e” (moments so special they are unrepeatable), “Fly once, fly always” persuaded them that once they experience the magical first time flying without the pain points they usually put up with, they would keep choosing Japan Airlines. Dynamic creative optimisation (DCO) delivered 3,000 content assets with precision and at scale to offer JAL as a better choice to different types of travellers from each market, at each stage of their journey to a range of destinations.
