Ancillary Revenue

What Is Ancillary Revenue?

Ancillary revenue is the income an airline generates from sources other than the price of the ticket itself. Rather than bundling every service into one fare, airlines unbundle optional extras and sell them individually, letting passengers choose — and pay for — only what they need.

Why It Matters

Ancillary revenue has grown from a marginal add-on into a major share of airline income, particularly for low-cost carriers (LCCs). Many ultra-low-cost carriers price their base fare very low and rely on ancillary sales to reach profitability, effectively using the base fare to capture a booking and then monetizing the trip through extras. Industry-wide, global ancillary revenue has been estimated at tens of billions of dollars annually, with the CarTrawler/IdeaWorksCompany Yearbook of Ancillary Revenue tracking the trend since the early 2010s.

Ancillary Revenue and Yield Management

Because ancillary products can be priced and sold independently of the base fare, they give airlines an additional lever for revenue management beyond traditional seat-inventory and fare-class controls. Merchandising ancillary offers at the right point in the booking and travel journey — search, booking, check-in, or at the gate — has become its own discipline within commercial teams, closely tied to how carriers approach yield management overall.
