The debate between GDS dependency and direct airline connectivity has grown sharper as NDC matures and airlines increasingly reserve their best fares and ancillary content for direct channels. But the decision is rarely as straightforward as the airline lobby makes it sound.
What GDS Actually Gives You
Global Distribution Systems provide a single integration point for hundreds of airlines, with standardized fare data, a common search and booking protocol, and centralized ticketing infrastructure. For most OTAs and travel agencies, the GDS fee is not just a booking cost — it pays for infrastructure, content breadth, and decades of airline connectivity that would take years to replicate.
The economics change, however, when your ticket volume is high enough that GDS fees become material, when your primary airline partners have moved meaningful content behind NDC, or when you want to offer ancillaries like seat upgrades and bag bundles as part of the booking flow rather than as an afterthought.
The Real Cost of Direct Connect
Airlines promoting direct API relationships tend to lead with the content advantages and underemphasize the integration overhead. A direct NDC connection to a single major airline requires certified NDC API integration, maintenance of that integration as the airline updates its API versions, operational processes for voiding and refunding without a GDS intermediary, and often a separate BSP or ARC relationship for ticketing.
Multiply that by a dozen airlines and you have an engineering problem, not a distribution strategy. Most travel companies that have moved aggressively to direct connect have found the operational complexity underestimated relative to initial projections.
A Hybrid Architecture Makes More Sense
The answer for most travel companies is a hybrid model: GDS as the backbone for breadth and operational simplicity, supplemented by direct API connections to the three to five airlines that represent your highest volume or that have moved exclusive content to NDC channels.
This requires a technology layer that can handle both protocols — routing search queries to the right source based on airline, and presenting unified results back to the booking workflow. Building that layer well is non-trivial but far more manageable than going fully direct across all carriers.
What to Watch in 2024–2025
IATA's NDC maturity targets, coupled with airline surcharges on GDS-distributed content, will push more volume toward direct APIs. Watch specifically for your highest-revenue airline partners — if they begin surcharging GDS content or restricting ancillary merchandising to NDC, that is the trigger to begin a phased direct integration, not a wholesale GDS exit.
