From baggage fees to in-flight meals, and even loyalty-based perks, these “optional” extras have evolved into a $148 billion industry for airlines alone. But the secret isn’t just in offering them – it’s in how they’re priced and presented.

The Structured Pricing Framework
Pricing ancillaries isn’t about guesswork – it’s about aligning costs, perceived value, and strategy in a way that feels both fair to the customer and profitable for the business. The four pillars are:
- Costs – The absolute baseline. This includes the direct expenses involved in offering the ancillary – such as the incremental fuel and admin costs for an extra legroom seat – but excludes fixed overhead like aircraft maintenance. If the seat upgrade costs the airline $10 in real terms, the price must be higher to maintain margin.
- Customer Value – This is what customers feel the upgrade is worth. For example, business travelers may be willing to pay $30–$40 for more space and productivity, while leisure travelers might cap out at $20–$25. Data-driven segmentation ensures the price sits at the sweet spot for multiple audiences.
- Reference Prices – Customers compare. They remember what they paid last time or what competitors charge. If a rival airline offers extra legroom at $29, pricing yours at $25 can create a perception of value while still delivering profit.
- Value Proposition – This is the brand alignment piece. A low-cost carrier positions ancillaries as affordable upgrades (“comfort without breaking the bank”), while a premium airline may present them as exclusive enhancements.
Example in Practice: A $25 extra legroom seat works because it clears its cost base, falls within both business and leisure traveler willingness-to-pay, beats key competitor pricing, and reinforces the airline’s promise of delivering affordable comfort.
The Psychology Behind Buying Extras
Even a perfectly priced ancillary won’t sell without understanding the human mind. Airlines use behavioral economics to nudge passengers toward saying “yes” to add-ons:
