What is Flight API? Use for Travel Itinerary Making Platforms


A flight API is a game-changer for digitally knowledgeable travelers in search of the best flight information. Check it out.

Flight API Integration enables travel agencies and online travel companies to connect their flight reservation systems to multiple flight suppliers. This integration enables travel companies to access real-time flight schedules, availability, prices, and other content from multiple airlines in a single location.

I. What is Flight API? 

Flight API is a tool that extracts flight information data including pricing, location, schedule, and airport codes. With the aid of flight API, travel agencies, OTAs, and flight booking portal owners obtain flight-related information to provide their consumers with the best experience possible. This includes information regarding one-way, round-trip, global flight data, and specific countries.

In addition, flight API integration is the process of integrating Flight API with booking websites, booking portals, and OTAs to obtain real-time flight data in seconds.

If you are a travel agency or a developer creating a flight booking portal, Flight API is the most dependable API for providing global real-time flight data.

II. How does Flight API work?

1. Flight search engine

In the same way that online travel agents and review platforms provide prospective travelers with a plethora of hotel and dining options, the virtual domain comes alive with flight options.

The vastness of cyberspace can be overwhelming. Incorporating flight APIs into travel platforms simplifies the situation.

Prospective travelers can sift through this abundance of data and refine their queries based on specific origins, destinations, and travel dates, thereby transforming this massive amount of data into actionable results.

2. Flight tracking

Travel planners confront an ever-increasing demand to provide clients with real-time flight information, similar to how hoteliers sift through their competitors’ offerings to improve their own.

The challenge is not only to keep clients informed but also to provide them with the means to effectively strategize.

With Flight APIs available, travel planners can dispel the fog of ambiguity surrounding flight schedules.

3. Flight booking engine

Traditional in-person travel agency consultations are becoming vestiges of the past in an era where the digital landscape is filled with tools and technologies.

Flight APIs have revitalized this industry. By leveraging these APIs, travel platforms enable users to reserve their desired flights without multiple screens or superfluous redirects, ensuring a streamlined, user-friendly booking experience.

4. Flight data analysis

Data in its basic form can be intimidating. However, when properly harnessed, it becomes potent intelligence.

Consider how hoteliers deep-dive into reviews to decipher their competitors’ strengths and areas for development.

Likewise, flight APIs collect voluminous flight-related data. Travel platforms can sift through this data and deduce invaluable insights into flight pattern trends, such as identifying the airlines that consistently arrive on time and pinpointing airport peak hours.

This “smart data” derived from flight APIs has a significant impact on user experiences and strategic decisions.

III. Why flight API integration benefits the Travel Sector 

1. Real-time flight data

Information is the foundation of effective decision-making in the world of travel planning, which is swiftly evolving.

Flight APIs emerge as a valuable instrument for real-time flight data, requiring travel planners to conduct in-depth analyses of which services resonate with customers.

It is not only about speed but also about unmatched accuracy.

With Flight APIs, planners have direct access to the most up-to-date flight data, ensuring that their suggestions and plans are never affected by last-minute changes.

It’s analogous to continuously updating a menu based on customer feedback; it’s always precise and pertinent.

2. Flexibility

Flight APIs provide travel platforms with an unparalleled advantage: adaptability. Platforms are no longer limited by a one-size-fits-all model.

After conducting a competitive analysis, they can refine their offerings and customize their services by leveraging these Flight APIs.

Whether emphasizing last-minute flights for impulsive travelers or providing intricate filters for meticulous planners, the platform can adapt to the traveler’s preferences.

3. Cost-effectiveness

The business world is not only about what you provide but also how you spend your money. 

Why invest in complex data collection systems in the realm of flight data integration when flight APIs offer a streamlined, cost-effective alternative?

It is akin to intelligently investing in amenities that guests truly value, having observed their absence in competing hotels. By employing Flight APIs, travel platforms can reallocate funds to other innovations, knowing that they have secured flight data at a fraction of the potential cost.

IV. Types of flight booking API 

1. Direct airline API

Provider of airline API or the airlines themselves offer direct airline API. The direct API integration of airline reservation systems eliminates the conventional distribution channel, allowing OTAs and TMCs to deal directly with airlines. In general, OTAs and TMCs integrate with corporations that can conduct direct business with airlines. 


The global distribution system provides the global content of flight inventory. In general, the inventory of all full-service carriers and some low-cost carriers affiliated with GDS is accessible. Currently, there are three major GDS API providers, which are as follows:

_ Amadeus

_ Galileo

_ Sabre

OTAs and TMCs can choose between Amadeus API Integration, Galileo API Integration, and Sabre API Integration for displaying the results, or they can combine them.

3. Third-party API 

There can be many third-party API providers in a country. The integration of a direct airline and GDS is typically costly, so the incorporation of a third-party API is a preferable alternative. It is an excellent option for mid and small-size OTAs or TMCs.

4. Flight meta-search API

This is a novel travel industry trend-setter. A recently developed meta-search API integration gathers data from various OTAs and presents it to the consumer so they can compare the price and amenities offered by various portals to make a more informed choice. Travel agents who wish to offer this service can either develop their metasearch engine or acquire API from an existing metasearch engine.

V. Is there an API to get real-time flight data analysis? 

The answer is YES. Real-time flight data tracking is an important feature in the flight search engine since it provides end-users with the most recent flight prices and other essential information. Check out the following Flight Search APIs offering real-time price data: 


1. FlightAPI

FlightAPI’s intuitive and user-friendly interface is its defining characteristic. This API is excellent for tracking flight prices in real time as it provides rapid and accurate data.

In addition, it is inexpensive and offers 30k API calls for only $49, making it an ideal solution for platforms with a large user base that requires extensive pricing tracking and comparison capabilities.

2. Kiwi API

This API provides real-time flight, pricing, and routing information. It is possible to set up price alerts for specific itineraries, but it does not provide extensive coverage for every airline in the world.

3. Amadeus API

Amadeus API provides real-time flight pricing tracking that returns accurate and current fare data. It is capable of returning complex flight fares, making it suitable for various applications. Developers unfamiliar with flight search APIs may find the extensive features and sometimes complex documentation to be a bit of a challenge.

4. Sabre API

This is a potent tool that provides access to comprehensive flight data in real-time. It provides dynamic pricing, detailed flight information, and adaptable routing to accommodate various flight search needs. However, its extensive feature set may appear complicated to novices.

VII. How do we integrate Flight API into the client’s flight websites? 

In the flight API integration, two parties are involved. Therefore, how you establish the connection will hinge on your goals and the API you choose.

Start with you. What is your flight’s website address? Do you want to facilitate booking or provide only flight-related information to your users? Are you targeting specific territories or do you intend to provide service globally? Budget and resource limitations are not the least of our concerns. Based on these details, you will select an API with the appropriate capabilities and coverage.

Whether you choose to integrate with a GDS, a tech service provider, an online travel agency (OTA), or a metasearch, the integration process will vary. For example, GDS will provide you with pools of raw airline data, whereas OTAs and metasearch have it organized in their unique manner. 

Once you have identified the platform from which you wish to extract data, review its API documentation and, if available, experiment with its test version. You will need an HTTP client to perform API calls.

Having determined that your website will benefit from using this API, obtain the API access key and determine whether the provider offers integration assistance or a pre-built API connection. If not, you may involve an outside integrator. Before the release, ensure that you have independently validated the API responses.
