Rocket Fuel was hired by Scandinavian Airlines (SAS) to increase flight bookings and achieve a positive return on investment. Initially using only prospecting new audiences, Rocket Fuel delivered a cost per acquisition (CPA) 63% better than the goal. Based on this success, SAS then had Rocket Fuel implement retargeting to utilize its full-funnel approach, and the monthly spend increased 72%. Through artificial intelligence and tracking pixels, Rocket Fuel analyzed user attributes and behaviors. This allowed Rocket Fuel to lower the CPA further, achieving a CPA 38% better than the blended goal. Key results showed users near airports were more likely to convert.
