What Is NDC? A Complete Guide to the Future of Airline Distribution

The way airlines sell and distribute flights is undergoing a massive shift.

At the heart of this transformation is NDC—short for New Distribution Capability—a modern industry standard developed by the International Air Transport Association (IATA).

NDC gives airlines more control over how their flights and services are sold. It empowers travel agents with better data, enables richer customer experiences, and opens the door to dynamic, personalized offers across booking platforms.

In this guide, we’ll cover:

• What NDC is and how it works
• The key problems it solves in the airline industry
• Why airlines and travel sellers are adopting it
• Real-world adoption stats as of 2024
• What to expect as we head into 2025 and beyond

What Is NDC in Airline Distribution?

New Distribution Capability (NDC) is a data transmission standard developed by IATA to modernize how airlines share content with third-party sellers.

Instead of relying on outdated legacy technology, NDC uses XML-based APIs to deliver real-time pricing, branded content, and personalized offers to:

• Travel agencies
• Online travel agencies (OTAs)
• Corporate booking platforms
• TMCs and consolidators
• NDC aggregators

This direct connection helps unlock rich merchandising features that weren’t possible with older formats like EDIFACT, which has been in use since the 1980s.

What does NDC stand for?
NDC stands for New Distribution Capability, a standard created by IATA to improve airline distribution through third-party channels like travel agents and OTAs.

Why Was NDC Created?

Legacy systems were never designed for modern retailing.

Airline content has historically been distributed via Global Distribution Systems (GDS) like Sabre, Amadeus, and Travelport—platforms built on EDIFACT, a rigid messaging standard that limits personalization, speed, and visual content.

As travel went digital, these systems couldn’t keep up. Travelers expected more. Airlines needed to evolve.

Core limitations of GDS systems:

• No images or branded visuals
• Static pricing and limited customization
• Generic offers for all passengers
• No dynamic merchandising or bundling
• Slower updates for availability and fare rules

NDC addresses these issues by giving airlines more control over content and pricing—even when it’s sold outside their own websites.

Why is NDC important?
NDC gives airlines the power to sell products the way retailers do: visually, dynamically, and with greater personalization.

How NDC Works (in Plain Terms)

Instead of publishing fares to a GDS and hoping the content remains intact, NDC lets airlines send real-time offers directly to travel sellers via modern APIs.

These offers include:

• Branded fare families (e.g., Basic, Flex, Premium)
• Dynamic ancillaries (bags, seats, Wi-Fi, lounge access)
• Loyalty-based pricing
• Route-specific promos or bundles

Everything can be personalized for the traveler—based on status, past behavior, or corporate policy.
