How does your retailing stack up?
Industry-wide benchmarks across attach, RPK, and merchandising velocity — drawn from anonymized aggregates across the AncillaryOffers platform.
| Metric | Median | Top quartile | Top decile |
|---|---|---|---|
| Ancillary attach rate (overall) | 31% | 47% | 58% |
| Bag attach rate | 24% | 36% | 44% |
| Seat attach rate | 29% | 42% | 55% |
| Bundle attach rate | 19% | 31% | 42% |
| Lounge attach (premium cabin) | 11% | 22% | 33% |
| Ancillary RPK as % of total RPK | 9.2% | 13.4% | 18.0% |
| Concurrent merchandising experiments | 12 | 47 | 120+ |
| Time from idea to live experiment | 11 days | 2 days | <24 hours |
How we computed these.
The numbers here are aggregates of customers running on the AncillaryOffers platform between Q3 2025 and Q1 2026. Cohort sizes are large enough that no single customer can be re-identified from any cell.
Median, top quartile, and top decile are computed across customers — not across bookings — so a single high-volume customer can't dominate the distribution.
Attach rates measure the percentage of bookings that include at least one of the named ancillary type. RPK percentages use the customer's own RPK definition mapped into our semantic layer.
Merchandising velocity counts only experiments that ran for at least 72 hours and reached statistical convergence.
