How do online travel agencies make money? Markup, commission and service fee models explained

The five revenue models

Almost every travel business earns through some combination of the same five mechanisms. Understanding which one carries your profit tells you what to sell and what to automate.

Supplier commission is the classic model: the supplier sets the public price, you sell it, they pay you a percentage. Simple, transparent to the customer, and shrinking — airlines cut base commission decades ago and hotels have squeezed it since.

Markup on net rates is where modern agencies earn. You buy at a confidential net rate from a bedbank, DMC or consolidator and sell at your own price. The customer sees one number; the spread is yours. This is why access to net rates matters more than any software feature.

Service fees are charged directly to the traveller for your expertise or handling: a per-ticket booking fee, a visa handling fee, a change or cancellation admin fee, or a planning retainer for complex itineraries. On thin-margin products such as flights, the service fee often is the profit.

Ancillaries are the quiet winner: seats, baggage, insurance, airport transfers, car hire, activities and lounge access attached to an existing booking. Acquisition cost is zero because the customer is already buying, and margins are typically higher than the core product.

Packaging is the highest-margin model. Bundle a flight, hotel, transfer and two excursions into one price and the customer cannot price-compare the components. Package margin routinely doubles the sum of the parts sold separately — and in most jurisdictions it also brings package regulations, so price the compliance in.

Realistic margins by product

The table below shows typical gross margin ranges. Actuals vary by market, supplier relationship and volume, but the ranking is stable across the industry.

Where the money actually leaks

Gross margin is not profit. Three things quietly erode it. Payment processing takes 1.5-3.5% plus cross-border and currency conversion charges, which on a low-cost flight can exceed the entire booking margin. Servicing time — amendments, refunds, chasing suppliers — costs staff hours nobody attributes to the booking that caused them. And platform commission, where the software vendor takes a percentage of every sale, is a permanent tax on your growth.

That last one is worth modelling before you sign anything. A 3% platform commission on £1.5m of annual turnover is £45,000 a year — more than most agencies pay their best consultant, for software that costs the same to run whether you book ten or ten thousand.

How to increase margin without raising prices

Attach more per booking. An agency selling flight-only at 3% and an agency selling the same flight with a transfer, insurance and two excursions are in different businesses. Set markup rules by product and market rather than a single global percentage, so you take more where competition is weak and stay sharp where it is not. Charge a service fee openly on flights instead of pretending the fare is your margin. And price in the customer's currency to stop FX charges eating the spread.

Then automate the servicing. Every amendment handled by a self-service page rather than a staff member converts a cost line back into margin.

Keeping what you earn

The structural decision is whether your software takes a cut. Commission-based platforms feel cheap at launch and become your largest supplier cost at scale. A flat subscription means the markup you set is the markup you keep — 100% of it — and every extra booking improves your unit economics rather than the vendor's.
