What it means in practice
Ancillary revenue is the money a travel supplier makes on extras around the core product. For an airline it includes baggage, seat selection, and priority boarding; for a hotel it includes upgrades, breakfast, parking, and late check-out. Ancillaries often carry higher margins than the base fare or room, so they are a major focus of revenue strategy.
For affiliate programs, ancillaries expand what a partner can be credited for. A program can pay CPA or a share on attached products like travel insurance and transfers, not just the core booking, which raises the value of each referred traveller. This is closely tied to dynamic packaging, where extras are bundled at the point of sale.
A travel brand running its own affiliate program can set per-product commission across the core booking and its ancillaries, so partners are rewarded for the full value of the trip they drive.
How Track360 handles this
Track360 supports per-product commission across the core booking and attached ancillaries, so an operator can reward partners for insurance, transfers, and upgrades as well as the primary product.
