What Is NDC in Travel And Why It Matters for Your Corporate Booking Program

Your Travel Management Company (TMC) keeps mentioning NDC on quarterly calls, your Online Booking Tool (OBT) vendor references it in product updates, and TMC NDC bookings increased 500% between 2022 and 2024 per NDC adoption data. Yet only 32% of travel managers say their TMC has communicated NDC plans adequately. If you're already fighting low OBT adoption and high call-in costs, NDC confusion compounds the problem by fragmenting your spend data, weakening policy enforcement, and creating duty of care gaps you'll have to explain to finance.

This article breaks down what NDC actually changes for corporate travel programs, covers four program-level impacts and five questions to ask your TMC, and gives you a framework to act before NDC readiness becomes a problem you didn't see coming.

What Is NDC In Corporate Travel and Why It Exists

NDC stands for New Distribution Capability, an XML-based data standard from IATA that changes how airline content flows from carriers to the booking tools your travelers use.

For decades, airline content has moved through GDS platforms using EDIFACT, a legacy architecture that constrains what your corporate OBT can display. The result is a stripped-down shopping experience that looks nothing like airline.com. That gap drives leakage because travelers assume the managed channel is missing options.

NDC closes that gap by letting airlines transmit richer content, bundled fare families, ancillary catalogs, and personalized corporate pricing through the same indirect channels your TMC and OBT use. Whether your TMC has built that bridge is the question that matters for your program.

How NDC Changes Your Corporate Travel Program

NDC creates specific, measurable impacts on how your managed travel program operates. These four show up in your reporting, your policy enforcement, and your next conversation with finance.

Fare Comparison and Lowest-Fare Compliance

The "lowest logical fare" principle assumes all available fares appear in one place. Content fragmentation breaks that assumption. Different channels now surface different prices for the same itinerary, and that fragmentation keeps growing as a corporate travel challenge per this fragmentation report. If your OBT only shows GDS content, you miss lower NDC fares. If your TMC aggregates both but doesn't normalize the display, travelers can't make a policy-compliant choice. Either way, lowest-fare compliance numbers lose credibility.

Savings vary by carrier. Some programs see meaningful cost differences on specific airlines, while others see little or no savings, so your TMC should show you the breakdown for your route mix rather than making blanket NDC claims.

Fare Families and Travel Policy Enforcement

NDC delivers fare families, bundled products like "Economy Saver" (no bag, no changes) and "Economy Flex" (full flexibility, changes allowed). These bundles don't map to traditional fare class structures your travel policy was built around.

Your policy engine may not know how to evaluate a bundled NDC offer against a bare GDS economy fare. "Economy class required" stops being a complete instruction when economy has three sub-products with different included services and prices. That means updating policy language to specify acceptable fare families and whether bundled ancillaries require separate approval.

Ancillary Spend Visibility in Bookings

Under GDS distribution, ancillaries got handled post-booking, often on personal credit cards and invisible to your program. NDC pulls ancillary products into the shopping stage as part of a bundled fare comparison. US airlines collected a record $7.27 billion in checked baggage fees alone in 2024, as covered in this ancillary revenue report. That means spend that never hit your reporting before can now get captured at the time of booking.

Cost differences add up on competitive routes, with wide variation by airline, timing, and market. The catch is servicing. If a traveler's NDC booking gets disrupted, the rebooking process may not automatically transfer or refund those ancillary charges through the same channel, so the economics can change quickly.

Duty of Care and Traveler Tracking Gaps

New distribution channels disrupt the data flows your program depends on for traveler tracking. Mid-market programs rely entirely on their TMC's data feed for duty of care. SME programs lean on TMC-provided duty of care technology far more than large enterprises, which run standalone risk management platforms that ingest data from multiple sources, as shown in this SME report.

If your TMC's NDC data feed doesn't populate your traveler risk management system with the same completeness as GDS bookings, your duty of care program has blind spots. Don't assume the data flows correctly. Verify it with your TMC before a disruption forces the question.

Four Questions to Ask Your TMC About NDC Readiness

That communication gap won't close on its own. These four questions force specifics out of your TMC before vague NDC promises become a contract problem.

• "Can you show NDC and GDS content in a single display?" Side-by-side comparison is the prerequisite for valid lowest-fare analysis. If your TMC can't demo this today, your travelers can't make policy-compliant choices across both channels.
• "What happens to an NDC booking when a flight is cancelled?" Post-booking servicing remains a significant NDC gap, with current limits covered in servicing gaps. Ask for specifics on which airlines support automated NDC rebooking and which require manual agent intervention.
• "What is your NDC roadmap with specific quarterly milestones?" A written roadmap with named milestones, specific airline connections, and committed dates separates genuine plans from aspirational positioning.
• "Are you relying solely on GDS developments, or do you have independent NDC connections?" This reveals whether your TMC has a multi-channel content strategy or is passively waiting for their GDS partner to solve NDC for them.

Some TMCs have a financial incentive to delay fixing NDC servicing gaps, since broken online tools generate more profitable offline transactions. Broken online tools that force travelers to call in can cost your program $50 or more per transaction in added fulfillment costs. That gap should inform how you negotiate NDC milestones into your contract.

NDC Adoption Rates vs. Corporate Travel Booking Leakage

NDC crossed 21.5% of US agency transactions in June 2024 in NDC share, but your program's real exposure depends on how well your TMC handles content, servicing, and downstream data.

The bigger issue is off-platform booking. Travelers still go outside managed channels when they believe prices are lower or inventory is better elsewhere. NDC can reduce that perception by bringing more airline content into your OBT, but only if your TMC nails the integration well enough that travelers see the same value they expect from direct channels. Where booking friction and unclear policy guidance still undermine adoption, this OBT guide shows why the point of sale matters.

That's where Otto the Agent fits. Otto is an AI-powered travel assistant that books flights and hotels through natural conversation, remembers traveler preferences, and applies company travel policy on the fly. It pulls NDC and GDS content into a single conversational interface, so travelers see the full picture without going direct. Otto lives in the channels your travelers already use, routes every request through your managed infrastructure, and shows policy-compliant options with clear explanations before anyone hits "book." Travelers stay in-channel without wrestling a portal, and your adoption numbers show it.

Turn NDC Readiness Into Lower Leakage and Better Compliance

NDC is not an emergency for US corporate programs today, but it is a vendor-management issue you need to get in front of now. As content fragments across channels, fare comparison gets weaker, policy rules get harder to apply, and servicing data gets less reliable. When that happens, travelers lose confidence in the managed channel and leakage follows.

If unclear fare bundles are driving out-of-policy choices, Otto can ingest company travel policy and flag whether an option is within policy or out of policy with a clear explanation. That gives travelers a stronger policy signal at the point of booking, cutting confusion when NDC fare families complicate comparisons.

Start with Otto to make policy rules more visible during booking and keep travelers in managed channels as NDC reshapes your fare display.

FAQ

Does NDC replace the GDS?

No. NDC is an additional distribution channel. Your TMC should aggregate GDS and NDC content into a single display so travelers can make valid fare comparisons across both.

Do I need to update my travel policy for NDC?

Yes. Policies built around fare classes don't account for bundled fare families with varying service levels. Define which tiers are acceptable per cabin class so your policy engine can evaluate NDC offers correctly.

Should I switch TMCs if mine isn't NDC-ready?

Not immediately, but document the gaps. Start with the five questions above, set quarterly milestones, and escalate if your TMC can't demonstrate progress on content display, servicing, and data feeds.

How can I make policy rules clearer during booking?

Otto can surface your travel policy at the point of sale, showing travelers whether a fare family is in or out of policy before they book. That reduces confusion without requiring travelers to interpret bundled pricing on their own.

Will NDC increase my TMC transaction costs?

It depends on your airline mix. NDC can reduce costs on some routes, but NDC servicing often requires more agent intervention than GDS workflows.
