Skyline Air's 27% lift in bundle attach is the headline. The story behind the headline is more interesting — and more useful.
Skyline didn't change its fare family names. Light, Smart, Comfort, Flex are still the products travelers see. What changed is the construction of those products: each name now corresponds to a goal-driven, dynamically-priced bundle that's allowed to change weekly within margin and policy guardrails.
The biggest operational change wasn't technical. It was governance. Skyline moved from quarterly fare-family reviews to weekly merchandising standups. Revenue managers, ecommerce, and brand all attend. The agenda is two-thirds 'what shipped, what worked' and one-third 'what's next'.
On the technical side, the heaviest lift was the analytics consolidation. Before AncillaryOffers, Skyline had four separate definitions of 'bundle attach' — one in each of the systems that touched bundles. We collapsed those into a single semantic definition before we shipped the first experiment. That alone made the next six months possible.
The lift compounded because Skyline didn't try to find the one big bundle. They ran fifty to two hundred experiments per month. Most were small. The cumulative effect was a step-change in the underlying attach rate.
