Flight booking api integration

The integration of Flight Booking API gives users access to integrate with the airline inventory and distribution system using an interface. The user is able to search for flights, schedule, check price, availability, book flights, and also manage flight services all in one system. An integrated Flight Booking API will give users the ability to automatically pass flight information from the supplier into the booking application. This integration includes fast searching, real-time travel content, booking processes, fare management, passenger information, ticketing, and airline distribution processes.

What Is Flight Booking API Integration?

Flight Booking API Integration refers to the technical process where the flight booking site, application or travel management solution is integrated with an airline, flight content provider, Global Distribution System, NDC or another authorized air-content system using an Application Programming Interface. The process facilitates the communication of requests and receipt of data, including flight schedules and availability, flights prices and conditions, baggage information, passengers' needs, bookings and tickets.Flight distribution systems are becoming more structured in their interactions via APIs. For instance, IATA's New Distribution Capability is a standard of data transmission within the airline industry designed to facilitate communication and retailing between airlines and travel sellers.

1. Flight Booking API

A Flight Booking API is a type of connection between a travel portal or booking software application that interfaces with a system containing flight inventory or distribution. The interface allows the system to make flight queries and receive data in a structured format, including but not limited to the origin point of the flight, destination, time of departure, time of arrival, airline company, seat classes, flight availability, baggage policies, and other booking data. Flight Booking APIs serve as the technology behind many flight booking websites. Utilizing an appropriate API, travel companies can automate flight search and booking instead of managing flight schedules and rates manually.

2. Airline API Integration

The integration of Airline API means linking up the online travel agency with the flight data generated by the airlines or distributed by the airlines. Depending on the airline or the technology vendor, this integration could help access flight schedules, fares that the airline uses, seating availability, ancillary products, baggage policy details, booking functionality, and order management facilities. As airline retailing becomes increasingly focused on offers and orders, the airlines become able to offer more information-rich and better-structured information about their products through a modern distribution system.NDC & ONE Order are among such standards according to IATA.

3. Flight API Provider

The Flight API Provider provides the necessary connectivity and flight content needed by travel applications. Depending on the provider, this content could range from several airlines, flights, schedules, fares, inventory, fare rules, baggage, ancillaries, bookings, ticketing, cancellations, and flight modifications. The provider serves as the source through which the booking application sends the APIs to get the flight information. Selection of the right provider is determined by factors such as airlines covered, markets, fare content, booking capability, documentation, performance, and commercial arrangements. A good provider connection enables the travel application to show the flight information without holding an inventory of airlines.

4. GDS API Integration

GDS API Integration links a travel booking application to the Global Distribution System to provide access to the distribution of flights and features related to bookings. The technology of the Global Distribution System has been used to provide travel agencies and other travel sellers access to information about flight schedules, availability, fares, reservations, and ticketing. IATA describes a Global Distribution System as a service which enables travel agents to make bookings for tickets. Through GDS API Integration, a booking system will be able to process search queries, find available flights, confirm fares, reserve passengers, and manage the bookings process.

5. NDC API Integration

NDC API Integration enables travel companies to be able to integrate their systems with airlines' content that is distributed through the IATA's New Distribution Capability (NDC). NDC was created in order to enhance communication between airlines and travel sellers and facilitate airline product retailing. According to IATA, NDC covers various areas such as product differentiation, rich air content availability, transparent shopping, offer management, order management, and ancillary sales. Through NDC API Integration, travel companies can use airline offers with the help of current distribution processes and might get fare families, branded products, baggage, seats, ancillaries, and offers from airlines.

1. Features

Flight Search : The Flight Search process in Airline API Integration involves passing passenger details and details of the journey, including origin, destination, dates of travel, nature of journey, number of passengers, and cabin class to the airlines' or GDS APIs. Real-time data on flights available, fares, schedules, airlines, baggage policy, stopovers, and terms of fares is fetched. The data is processed, filtered, and sorted for presentation to the user to enable comparison of flights before making a booking choice.
Fare & Availability : In Flight Search API, Fare and Availability is the process where the availability of the flight is checked in real time along with checking seat availability, class, schedule, and prices of the selected route and selected date of travel. This API will provide information on the fare available, such as base fare, taxes, fee, baggage policy, refund policy, and overall amount payable. It will provide information on whether the seat is available or not in the desired cabin/fare class.
Fare Rules : Fare Rules in Flight Search API represent the airline regulations concerning a particular fare chosen by the user. They include various terms and conditions like cancellation fee, refundability, change fee, no show policy, ticketing deadline, baggage allowance and so on. Fare rules can usually be obtained from the airline or API/GDS provider based on the flight or fare chosen. They must be presented to the customer prior to booking confirmation so that he knows the restrictions and policies related to the fare purchased.
Booking Management : Booking Management in Flight Reservation API is responsible for managing the entire process of flight booking via APIs from airlines or suppliers. This component deals with the processes of booking creation, passenger information, price confirmation, PNR creation, ticketing status, booking fetching, booking cancellation, booking modifications, refund processes and payment references. This module ensures synchronization of booking data in real time through API providers, maintains necessary booking transaction data, booking history, failed and pending bookings, and provides an interface for administrators/agents to manage flight bookings.

The functionality supports real time fare validation, PNR lookup, ticketing, issuing of e-ticket numbers, update booking status, cancellation, reissuing of tickets, as well as management of the deadline of ticketing. The integration ensures accurate synchronization of passenger information as well as details of itinerary from one system to another using APIs.
