Phocuswright’s research team reveals that the global travel industry is starting the year on a strong foot, with total gross bookings estimated to hit roughly $1.67 trillion in 2025. International demand is picking up steam, and travelers continue to prioritize experiences in spite of economic and geopolitical pressures.
To make the most of this expanding market, online travel agencies (OTAs) have taken another step beyond simple digital transformation to become the undisputed gatekeepers of world tourism. As a result, the global OTA market has seen substantial growth. It was worth $996.12 billion in early 2026, up from $943.16 billion in 2025, and is predicted to reach $1.24 trillion in 2030 with a CAGR of 5.8%.

The latest trends show that OTAs remain at the center of global distribution; as of 2025, they generated approximately $408 billion worth of global bookings. That is, 1 in 4 of the travel dollars worldwide. However, their power is highly unbalanced: they are dominant in lodging (the cornerstone of OTAs’ profitability), modest in air distribution, and quite insignificant in cruise and rail. Industry forecasters indicate that OTA revenues will be climbing at 7–8% CAGR over the next decade due to the rise of mobile transactions, localization, and travel planning features enabled by AI.
In the meantime, the barrier to entry has never been so high. The Big Three (Booking Holdings, Expedia Group, and Airbnb) now hold the market. Booking Holdings is the leading OTA holding company, with a market share of around 40–45%, Booking.com dominating the online travel agency market, and a strong international presence. Expedia Group comes next with about 16–23% market share, which leads in the U.S. market, while Airbnb has a large specialized market position with around 17–25% in the alternative accommodation sector.
Meanwhile, tech giants such as Google are introducing Agentic AI tools that are threatening to change the way search works altogether. For aspiring entrepreneurs, this means the time of the generic travel portal is gone. To be successful in 2026, hyper-specialization, leaner operations, and a tech stack designed for AI are the keys.
In this guide, we outline the upgraded roadmap for building a competitive OTA in this tough but lucrative market. It also contains our ideas and recommendations on better ways to handle each step based on GP Solutions’ years of experience in supplying technology solutions for travel startups, including new OTA businesses.
Just as any journey starts with choosing the destination, a new OTA usually begins with defining the market you are going to operate in. At this stage, it is necessary to run a careful analysis and come to an all-round understanding of your market and potential clients. In a market where Expedia and Booking spent a combined $14.1 billion on marketing in 2024 alone, attempting to compete in travel in general is financial suicide. The only route available to a new business is to dominate a niche in which the giants are too broad to compete effectively.
It is important to consider various aspects, such as:
Finding niche markets is generally a viable approach. First of all, it offers an adequate response to the competition forced upon startups by bigger OTAs. Niche businesses can offer unique experiences that are tailored to the needs and expectations of specific, limited customer groups. Secondly, it is a reasonable way to avoid overspending on marketing while securing satisfactory conversion rates thanks to more targeted outreach.

Don’t know where to start with your OTA technology? We are here to help!
However, the mere choice of your niche can already become quite a challenge in itself. There are just so many options to consider! It makes good sense, in this case, to narrow down your list of options by leaving just the most promising at the moment and ideally in the foreseeable future.
Here are the hottest travel niches for 2026:

As the global temperatures increase, summer travel patterns are moving north. Coolcations (trips specifically designed to escape heatwaves) are exploding in popularity. Destinations such as Scandinavia, Alaska, and Northern Canada are experiencing a 35% spike in bookings, making it a prime opportunity for OTAs that specialize in temperate and nature-focused getaways.
In an age of hyper-connectivity, demand for digital detox is at an all-time high. This niche is focused on silent retreats, off-grid cabins, and sleep tourism. It is aimed at those travelers who now list “unplugging” as their main reason to vacation.

This is not so much about where people go, but how they book. A new wave of OTAs is coming on stream that use Agentic AI, autonomous agents that don’t just search for flights but plan and book complex, multi-city itineraries in seconds. Startups in the realm of concierge-style AI are gaining rapid adoption.
Travel inspired by streaming services and movies (the White Lotus effect) has gone from a micro-trend to a mainstream driver. 2026 travelers are planning their entire itineraries around filming locations, and OTAs need specialization to bundle these unique and hard-to-find experiences. Thus, for instance, filming for the new Potter TV series is set to bring the crowds again and even rescue Cornwall’s tourism industry.
Business travel has changed forever. We saw the rise of bleisure OTAs who appeal to the needs of remote workers and digital nomads seeking high-speed hotel Wi-Fi verified, co-working spaces booked, and long-stay discounts automatically applied.
Sustainable tourism remains a steadily growing trend in travel. It focuses on travel experiences involving activities that serve various social causes. Tourists are getting increasingly more concerned about how their journeys can be beneficial to local communities in post-pandemic times.
As part of it, eco-conscious travel continues expanding, with 35% of travelers planning food market experiences in 2026 around interaction with locals and cuisine.
The niche is projected to exceed $1 trillion worldwide by 2026 due to the focus on health, longevity, and mental balance. The Glowmads trend (beauty and wellness routines abroad) is changing itineraries, with social platforms such as TikTok influencing one in five bookings of the kind.
The list is not exhaustive, of course. There is group travel that is expected to grow from $391.36 billion in 2025 to $414 billion in 2026 (5.83% CAGR through 2035). Rail travel (especially luxury) is in a golden age. There are also ancestry travel and astro-cruising emerging as distinct 2026 niches. The choice is yours!
Accreditation is a unique number assigned to travel professionals in recognition of business trustworthiness. It remains the mainstay of legitimacy in the travel industry. First of all, it permits you to book travel, receive commissions, and, with some accreditations, issue airline tickets with the most established travel suppliers. Secondly, it is a powerful tool for building trust and credibility in the travel market.

The IATA ID remains the gold standard, giving you access to roughly 250 airlines and the BSP (Billing and Settlement Plan).

With all the perks, no wonder it is in the highest demand and really hard to get. It normally takes months of expectation prior to getting your approval. But before that, you need to demonstrate considerable experience in travel, obtain a business license, and also fulfill a set of other important criteria. All these complex requirements naturally make IATA a hard target for new businesses. But the benefits it brings definitely make it worth all the effort.
However, for a 2026 startup, getting full IATA accreditation can be too slow and costly (including hefty financial bonds). Most new OTAs now launch by teaming up with Host Agencies or Air Consolidators (like Mystifly or Duffel) to use IATA fares without the regulatory headache.
ARC is a US-only accreditation for travel agencies. Similar to IATA, it offers access to over 200 network operators and tools, as well as programs for credit card processing and anti-fraud services.
There are three levels of accreditation offered by ARC for various purposes. The traditional option does not require any prior experience in this field. However, there is the ARC Specialist exam that one of your employees needs to pass. It increases the costs and the waiting time to get your ID.
The high price combined with annual fees, as well as the strict application process, including interviews with agency owners, can create overwhelming obstacles for new OTAs. But just like IATA, it opens up great prospects and can serve as a source of trust and credibility for your business on the market.
TRUE accreditation is a great option for businesses operating in the travel agent niche. There are two levels of accreditation available: travel agency accreditation (which covers up to 5 travel agents) and host agency accreditation (accommodates up to 25 agents). It is mainly focused on the U.S. market. However, it recently shifted its focus and is now committed to operating globally.
The main advantage of the TRUE number is the possibility to closely work with smaller boutique tour operators that may not be the target audience for other prominent organizations offering accreditation in travel. Also, TRUE allows agents to interact with suppliers using net rates as an alternative to more common commission-based arrangements.
CLIA membership requirements are not so strict. Basic membership won’t require any significant experience from you or an entrance fee (it can be mandatory only if you go for the premium option).
If you plan to sell cruises (a sector booming with a younger demographic in 2026), CLIA is non-negotiable. It is accepted by 95% of cruise lines and is significantly easier to obtain than IATA.
It definitely is if you wish to cooperate with a GDS for flight content. Sabre or Amadeus will for sure demand an IATA ID from you. In other cases, an accreditation would still be great, but not obligatory to own.
When it comes to flights, startup OTAs often choose flight consolidators initially. These are companies like TravelFusion, Mystifly, XML.Agency, PKFARE, or others. Their business is based on buying large chunks of tickets from airlines at discounted (or ‘net’) rates and then reselling them to travel agencies. The end price for the latter is good enough to apply their own markups on top and still offer tickets to travelers at prices lower than the general market. The margins that agents earn on consolidator rates are usually lower compared to what they might count on with an IATA ID. But the time-to-market is much faster, and there is no need to spend heavily on getting your accreditation in place.
Joining a host agency is another working option to enter the OTA business without accreditation. It means you will operate under the umbrella of a travel company that already holds its own IATA ID. This is a relatively quick and convenient way to enjoy the key benefits accreditation has to offer, such as access to GDSs and lucrative airline rates. However, you will also need to comply with a certain set of qualification requirements (they may differ depending on the host) and pay fees for the host service.
It is a common story for startup OTAs to have limited initial budgets. That is why it is crucial for them to invest carefully to make sure they get the most out of every penny. On the other hand, it is also extremely important to plan and monitor your revenues properly so you can manage and distribute available budgets with utmost productivity.
A meticulous and conscious approach at every project stage is the only way to handle this challenge successfully. With that said, there are certain aspects of business and techniques that are worth specific attention as they’ll benefit your project the most in terms of adequate budgeting.
Marketing is usually the heaviest expense item, often reaching 50% of the total project cost. In 2024, the largest OTAs (Booking, Expedia, Airbnb, Trip.com) spent a record $17.8 billion on sales and marketing.
Investing your budget in merely driving the traffic to your portal from all possible sources will almost certainly lead to failure. It would be much smarter to develop a sound customer retention strategy before launching any traffic generation campaigns. Not only will this approach secure higher conversion rates, but it can also reduce marketing expenses and release extra funds to spend on better software or customer service.
For example, it is possible to achieve positive results with loyalty programs based on bonus points that can partially or fully cover the cost of a travel service. This is a crucial element for smaller businesses nowadays. Research indicates that 57% of travelers prefer OTA package deals, and loyalty programs can boost retention by approximately 52%. These programs can also be extended with volume discounts (for example, “7=6” on hotels), promo code distribution campaigns, etc. All these features can get almost fully automated, which means minimum manual effort from OTA staff.
Don’t build your business plan on flight commissions only. Pay more attention to non-air sales. You can certainly use flights as the hook to get the customer, but it is wiser to make money through the cross-sell of hotels and high-margin experiences.
Flights
Hotels/Lodging
Experiences/Tours
Razor thin, often 3–5%
Real profit, 12–15%
Best, often 20%+
Preparation and planning for your OTA software development or selecting your ready-made solution are everything. This is exactly why a properly conducted discovery phase should be an obligatory step in your startup building process. Ideally, it should cover a series of activities to build a complete project vision, define the full development scope, and, most importantly, draw up a well-balanced development budget. A discovery phase will help you to develop all-encompassing project estimates by approaching your project from both the business and technical perspectives. This is by far the only correct way to ensure reasonable financial planning.
As a software vendor with 20+ years in travel tech, GP Solutions would be glad to extend its Discovery & Analysis services to any OTA looking for profound estimates and thorough technical preparation.

The right way to start your travel software development

It takes a complex technical infrastructure to launch an OTA business. First of all, there has to be a high-performing and reliable booking engine at the core that would cover your booking flows for travel products — hotels, flights, activities, car rental services, or any other you might want to sell. Next, it also needs to be extended with a number of important functional blocks, such as reservation management modules, an inventory management system, a business rules engine for markups and commissions, a structured API for productive data exchange via B2C or B2B channels, and many more.
But the technical platform alone, however sophisticated, is not a 100% guarantee of success. Any implementation should be based on a reasonable strategy that can pave a much safer way toward a prosperous booking portal.
Here are a few practical strategic hints that can benefit the tech side of your OTA.
This is one of the key dilemmas to go through before any implementation takes place. A bad decision here usually causes lots of trouble. There are different reasons why people choose wrong — over-focus on a particular option, bad planning, poor work on requirements… But haste is by far the most frequent reason of them all.
Take a few minutes to read this article from our blog for valuable guidelines that can help you make the right decision.

Unsure which path to follow? Book a discovery call, and we'll help you figure out which scenario is your best fit.
It is common practice for startups to first enter the market with a Minimum Viable Product, or MVP. It denotes a software version that offers just enough features for early customers who can provide valuable feedback for future product development. This technique is created to avoid excessive initial efforts. It allows you to make sure that your core OTA concept really works before you launch any full-scale development.
Various sources point out the rising demand for mobile connectivity among travelers.
As mobile devices have become part of ourselves, tech giants enter into user-friendly partnerships to make the travel booking experience even smoother. For instance, in August 2025, TikTok partnered with Booking.com to offer in-app hotel booking so that users could book their stay without leaving the app.
These developments vividly demonstrate the importance for travel businesses to have a mobile option in our connected world. For startup OTAs, it is possible to start with a mobile web version or an adaptive layout first to keep initial efforts to a minimum. Native Android and iOS apps can be released at later stages. Anyways, mobile interfaces should be kept in order at all times.
The heart of your OTA is no longer a search bar because a future-proof business should be fueled by recommendation engines and AI-driven chatbots. 66% of Gen Z travelers are now expecting to receive personalized suggestions and tailored experiences. Your tech stack needs to make use of machine learning to make predictions of preferences (i.e., suggest use of a quiet room for a business traveler or a hostel stay for a student party).
The crowning jewel of 2026 OTAs is the integration of LLMs that enable users to say, “Find me a week-long trip to a cool climate in July for under $3,000,” and receive a bookable itinerary instantly. One of the latest examples is Trip Matching, launched by Expedia in 2025, an AI-powered feature to transform Instagram Reels into bookable itineraries.
No OTA website can operate as an isolated system. Every modern online booking portal requires a number of integrations with external systems to perform its basic routines — to display travel product offers, process bookings, accept payments, compile performance metrics for the management board, etc.
An overwhelming majority of OTAs rely on third-party suppliers for travel data. This group of entities includes various types of travel distribution platforms such as GDSs, bedbanks, flight consolidators, other OTAs, etc. They are convenient to work with because they deliver content and confirm bookings almost fully automatically via specialized APIs. There is no need for lots of manual work, as in the case with your own travel inventory.
The airline business is experiencing a major change and transformation in the way information is presented. The distribution is shifting from GDSs towards NDC (New Distribution Capability), which is an XML-based IATA standard that allows airlines to provide richer content and personalized offers. Although Amadeus, Sabre, and Travelport remain the giants, 2026 is opening new opportunities for NDC (New Distribution Capability) aggregators. These enable you to provide rich content (for instance, you can choose particular seats or meals), which is something that legacy GDS connections often miss.
To have competitive rates on hotels, you need connections to wholesalers such as Hotelbeds or WebBeds. However, newer API-first suppliers are making it easier to integrate diverse inventory without massive setup fees.
Many OTAs have turned to use travel API aggregators quite extensively in recent years. This is a great opportunity to cut down drastically on your API integration efforts by unifying multiple travel suppliers under a common product-based API. For example, a single hotel API integration can put you through to Hotelbeds, Ratehawk, Webbeds, and many other suppliers all at once in real time. This is something really worth exploring while planning integration efforts for your OTA.
Online payment options are what really wrap up the one-stop-shop experience that is so highly valued in OTAs. The market of payment gateways is so rich that it is really easy to get lost in it. We hope these few guidelines will help narrow down your search:
Take, for instance, the latest integration of the global payment system Exactly.com with our in-house travel management platform, GP Travel Enterprise. The team behind the payment gateway offers global support and a wide range of services at competitive prices.

Integration of a CRM system can benefit your OTA business in many ways. Systems of this type are designed to provide valuable insights into customer behavior and sales data. They help to determine the most promising segments of your audience and indicate opportunities to yield even better financial returns from your current customers.
Most popular CRM systems like Salesforce or HubSpot may not be the cheapest pieces of software. But if used properly, they can (indirectly) save you lots of money and constantly open new areas to generate extra profit.
OTAs may frequently use other systems for their day-to-day needs. These may include accounting systems, reporting and analytical tools, BI solutions, etc. A properly built export API can make the process of using them much easier as soon as it can:
Thus, it makes sense to add this item to your OTA tech checklist.
Last but definitely not least is the level of service and experience your OTA can offer to customers. Travelers of today are very demanding and only willing to go for top-notch service that flows like clockwork. This effect can only be reached by making regular contributions to the following aspects.
Successful online booking portals usually feature the following UI elements:

Each of these points needs constant attention and improvement in order to keep up with the market trends. Otherwise, your portal runs the risk of falling behind.
Every visitor to your website must feel instantly at home. The credibility of this sort can be developed with the help of various activities and techniques, such as:
You can’t avoid chats in the travel industry, as users always have different inquiries and questions. Don’t forget that your users have a vacation mood, so customer service should be as friendly as possible.
Let’s have a look at a couple of successful implementations of AI-based customer service:
