Case Study: Porter Airlines Inc. achieves a 35% reduction in CPA with StackAdapt

StackAdapt Helps Porter Airlines Decrease CPA by 35%

Porter Airlines Inc., a Toronto-based carrier known for short-haul hospitality, wanted to drive engaged visitors to its new re:view lifestyle blog and convert that interest into more flight bookings while lowering acquisition costs. To prove the blog’s value and find an efficient media mix, Porter tested multiple paid channels and needed a partner to target prospective travelers and reduce cost per acquisition (CPA).

StackAdapt built a proprietary intent-based audience using machine learning and NLP, creating a Custom Segment of over 5.1 million people actively showing intent to book and serving premium in-feed native ads across 30+ native networks to drive traffic to re:view. The StackAdapt platform outperformed other paid channels like Google and Facebook, delivering a 35% reduction in CPA on flight bookings, shortened conversion windows (3–4 days), and measurable increases in bookings.
