Online travel agencies do not own a single hotel room, airline seat, or cruise cabin. Expedia Group, Booking Holdings, and every OTA in their combined subsidiary networks are software companies. They operate websites and apps that sit between the supplier who owns the inventory and the consumer who wants to book it. Their entire revenue model depends on one thing: the margin between what they pay for travel and what they charge you for the same travel.
That margin — extracted billions of dollars at a time — is the OTA business model, stated plainly.
The Two Revenue Models Every OTA Runs
Online travel agency revenue comes from two distinct mechanisms, and most major OTAs use both simultaneously.
The merchant model: The OTA negotiates a wholesale (net) rate directly with a hotel or resort. It then sets its own consumer-facing price — higher than what it paid — and keeps the spread. The OTA is the merchant of record: your credit card is charged by the OTA, not the hotel. The difference between the net rate and the price you see on screen is pure margin.
The agency model: The hotel sets the consumer price and pays the OTA a commission — typically 15 to 25 percent — on every completed booking. Here, the hotel is the merchant of record, but the commission is still baked into the rate you pay. Hotels don’t absorb that cost out of goodwill. They price their rooms to cover it, which means the commission is effectively passed through to the consumer.
Under both models, the consumer pays a price that includes the OTA’s cut. The only question is whether the markup is applied by the OTA directly or by the hotel on the OTA’s behalf. Either way, you are funding the OTA’s operation every time you book.
Where Those Billions Actually Come From
Expedia Group posted more than $1.2 billion in annual profit last year while spending roughly $7 billion a year in sales and marketing to keep consumers flowing through its booking funnels. Booking Holdings posted $5.4 billion in net income. Combined, these two companies extracted more than $6.6 billion in profit from the travel-buying public in a single year — and neither company owns a single room, seat, or cabin.
Every dollar of that profit originated in the spread between wholesale rates and retail prices. The OTA business model is, at its foundation, a markup machine. The scale of the machine is what most consumers never see.

The Subsidiary Illusion
Most consumers believe they are comparison-shopping when they check prices across multiple travel sites. What they do not realize is how many of those sites are owned by the same two companies.
Expedia Group owns Hotels.com, Hotwire, Trivago, Travelocity, Orbitz, CheapTickets, and CarRentals.com. Booking Holdings owns Booking.com, Priceline, Kayak, Agoda, and RentalCars.com.
Trivago is the most instructive example. It presents itself as a neutral price comparison engine — a tool that helps consumers find the lowest rate across “multiple sites.” But Expedia owns Trivago. And most of the sites being compared are also Expedia properties. The consumer feels empowered by the act of comparison while never leaving a closed ecosystem where every displayed price includes an Expedia-tier markup.
This is not a conspiracy theory. These are publicly traded companies with documented ownership structures filed with the SEC. The information is available to anyone who looks. Most people never look, because the branding is designed to make each subsidiary feel like an independent competitor.
The Pricing Theater That Keeps It Working
OTAs have refined their consumer-facing experience over two decades and billions of dollars of conversion optimization. Several specific tactics keep the markup invisible.
Anchor pricing: A crossed-out “original” price appears next to the offered rate, creating the visual impression of a discount. These anchor prices are frequently inflated beyond any real market rate — they exist to make the OTA’s retail price feel like a deal rather than a markup.
Hidden fee sequencing: Base prices displayed in search results often exclude taxes, resort fees, and service charges. Those costs appear only at the final checkout screen, after the consumer has invested time selecting a property, choosing a room, and entering personal information. The sunk-cost psychology is deliberate. By the time the real total appears, most people complete the booking rather than start over.
Urgency manufacturing: “Only 2 rooms left at this price.” “17 people are looking at this property right now.” These notifications create artificial scarcity pressure designed to override the consumer’s willingness to comparison-shop outside the OTA ecosystem. Whether the claims are accurate is secondary to their function: they compress the decision window so the consumer books before questioning the price.
None of these tactics change the underlying rate. They change how the consumer feels about paying it.
What OTAs Actually Provide
To be clear about what you get for the markup: OTAs provide convenience. Before the internet, booking travel required a phone call to a travel agent or a hotel’s reservation desk. OTAs made it possible to browse thousands of properties, compare amenities, read reviews, and book from your couch. That was a genuine innovation in the early 2000s.
But convenience and price are different things. The OTA revolution gave consumers easier access to travel inventory. It did not give them cheaper access. The markup that once went to brick-and-mortar travel agents simply migrated online — and in many cases grew larger, because the scale of digital distribution let OTAs extract margin across millions of transactions per day.
The question worth asking is whether the convenience of an OTA booking interface is worth the cumulative thousands of dollars in markup a regular traveler pays over a lifetime. Whether OTAs are measurably more expensive than booking direct with the hotel is a question with a specific, documented answer — see Are OTAs More Expensive Than Booking Direct.
The Third Option Most Consumers Have Never Heard Of
The OTA model depends on consumers believing there are only two choices: book through an OTA or book directly with the hotel. Both options operate at retail pricing tiers. The OTA layers its margin on top of the wholesale rate. The hotel’s direct rate typically matches or slightly undercuts OTA pricing to maintain rate parity agreements — but it is still a retail rate designed to protect the hotel’s OTA distribution relationships.
What neither option provides is the wholesale rate itself — the net price the hotel charges its distribution partners before any consumer-facing markup is applied.
That net rate has existed for decades. It is the foundation of the entire travel distribution chain. Travel agents access it through consortia. OTAs access it through supplier agreements. The only people who have never had access are the consumers actually paying for the travel.
HappiTravel changes that equation. With direct commercial agreements across 200+ wholesale suppliers, HappiTravel surfaces the actual net rate — the same pricing tier the largest OTAs negotiate — and passes it directly to members at $29.99 per month. No markup layered on top. No anchor pricing theater. No hidden fees revealed at checkout. The wholesale rate, displayed next to live retail comparisons from Expedia, Hotels.com, Agoda, Priceline, and Booking.com so members can verify the difference themselves.
The OTA business model works because most consumers do not know the wholesale rate exists. Once you see it, paying retail stops making sense.
