Case Study: United Airlines boosts MileagePlus adoption and member retention with SundaySky

United Airlines - Customer Case Study

United Airlines sought to modernize its MileagePlus loyalty experience after historically sending physical milestone packages, a shift that was accelerated by the COVID‑19 pandemic. The challenge was to replace costly, one‑size‑fits‑all mailings with scalable, personalized digital engagement that educates members and celebrates tier milestones.

Using the SundaySky Platform, United delivers personalized video experiences for onboarding, benefits education, and tier‑celebration messages, and builds targeted B2B videos for corporate travel directors. The approach increased digital tool adoption, deepened engagement and retention, and provided a cost‑effective way to show appreciation and improve the overall customer experience.
