NDC adoption surged among traditional travel agencies in 2025, according to reporting from Travel Weekly, marking a decisive shift in how a segment long characterized by legacy booking workflows now sources airline content.

The finding matters because traditional agencies have trailed online travel agencies and self-booking tools in NDC uptake since airlines began pushing content through the XML-based standard. If brick-and-mortar and managed-travel intermediaries are now adopting NDC-enabled content at scale, the balance of power in air distribution shifts along with them — away from legacy GDS integrations and toward direct connections, aggregator platforms, and the airline-controlled offer constructs that NDC makes possible.

Travel Weekly's report identifies 2025 as the year this movement among traditional agencies moved from experimentation to meaningful volume. That distinction carries revenue consequences across the distribution chain. Airlines have spent the better part of a decade building the commercial case for NDC: richer merchandising, targeted offers, ancillary revenue attached at the point of sale, and lower distribution costs per booking compared with legacy channel fees. Adoption by traditional agencies — rather than only the large online players — widens the surface area over which those economics can operate.

For sellers of travel, the shift changes the cost and content picture in parallel. Agencies that connect through NDC aggregators or direct airline links gain access to fare families, bundled ancillaries, and in some cases content that carriers have withheld from legacy channels. They also absorb new obligations: servicing workflows that vary by carrier, after-sales processes that legacy infrastructure handled automatically, and commercial terms negotiated airline by airline rather than through a single GDS contract.

The report's framing — a surge, not incremental growth — suggests traditional agencies crossed a threshold in 2025 rather than continuing the slow, pilot-level adoption that has defined the segment since airlines first began incentivizing the channel. For the GDS companies, that erosion matters directly: traditional agencies remain a core source of booking volume and segment-based revenue, and every point of share that moves to NDC-enabled sourcing pressures both the transaction fees and the content exclusivity that underpin the legacy model.

Travel Weekly's finding also carries weight for airline distribution strategy. Carriers have long argued that broad agency adoption would unlock the full merchandising value of the standard — dynamic offers, personalized pricing constructs, and ancillary attach rates that legacy EDIFACT messaging cannot carry. A 2025 surge among traditional agencies indicates the channel finally has both the tooling and the commercial motivation to transact on those terms.

Interrogating the claim requires the discipline that any adoption statistic demands. "Adoption" can mean an agency has made a single NDC booking, or that a material share of its air volume flows through the new channel. The distinction determines whether the 2025 surge represents genuine distribution shift or a broadening of trials. Travel Weekly's characterization points to substantive movement, but agencies, airlines, and technology intermediaries evaluating the trend should weigh the underlying share-of-bookings data against bookings-base definitions before drawing conclusions about the pace of legacy-channel displacement.

What is measurable in the finding is directional and consistent with the pressures reshaping air distribution: airlines continue to move content, carriers continue to price legacy channels less attractively, and agencies of every type are recalculating where their booking economics work best. A surge among the slowest-moving segment signals that the calculation has changed.

The practical question for the trade now shifts from whether traditional agencies will adopt NDC to how fast the channel's booking share migrates, which aggregators and technology providers capture the servicing burden that comes with it, and whether GDS operators can hold content and volume as the standard scales. Travel Weekly's 2025 finding suggests that race has already begun in earnest.
