Why Travel Agencies Need the Best Flight Booking API for Growth?
Before we get to the good stuff, let’s first try to understand what the whole facade about. Why do so many travel agencies are rushing to integrate API for booking flights into their portal? Here are some reasons why:
1. Updated Information
First of all, flight booking API enriches the travel portal with real-time information. This allows their customers to check flight flight availability, pricing, and schedules with maximum accuracy. What’s more, travel portals and OTAs can use this information to notify their customers about fare drops or seat availability.
2. Reduced Manual Work
API for booking flights is equally advantageous for businesses as well. They save the teams from the manual hassle of handling user data like cross-checking airline websites or manually updating reservations. This helps the business to focus on important tasks like making customer relationships stronger than before.
3. Error-Free Bookings
It’s very important for small B2B and B2C businesses to handle their operations without any errors. When done manually, there are chances of misspelling a name or recording an incorrect date. But not with a flight booking API as it validates data in real-time resulting in reducing error by over 90%.
4. Customized Packages
Another important benefit that businesses get by using a flight booking API provider is the ability to offer multiple customized packages. Portals often bundle flights with hotels, car rentals, or experiences, creating tailored itineraries that meet unique client preferences. Some even provide an end-to-end travel solution that offers everything such as flights+activities+hotel.

Key Features Travel Agents Should Look for in a Flight Booking API
Choosing an all-rounder API for an air ticket booking portal is not so simple. There are multiple factors to be considered before making this decision. To help you with the same, below we’ve discussed some prominent features to look for in a flight booking API solution that sets the best apart:
Real-Time Data
The first and maybe the most crucial element of a third-party API is data. Customers should get access to real-time flight data when they visit your portal. Everything from live status to fares should be updated regularly. Hence, look for flight booking API providers like OneClick, who provide updated data to avoid overbookings and missed opportunities.
Global Coverage

Hence, it’s important to choose a flight booking API provider that enables your portal to provide competitive fares, seasonal discounts, or loyalty rewards. Dynamic pricing helps to connect with the users on a deeper level and fosters strong relationships.
Easy Integration
Before integrating an API into your portal, carefully analyze its documentation. You must only consider the flight booking APIs that come with pre-built SDKs as the integration process becomes seamless with existing booking engines or CRM systems.
Customization
Consider the possibility of upgrading your portal or API integration with time. With a growing user base, you’ll require it in the future. Hence, only go for API for booking flights that provide the ability to white-label the API, add branded interfaces, or modify the workflow. This will help you in the long run.
