For decades, the GDS acted as airlines primary gateway to travel sellers. That model has been replaced by a complex distribution landscape, characterised by a growing mix of channels, APIs, and content fragmentation. Within this context, non-GDS aggregators are gaining relevance. For some airlines, the newer aggregators provide a practical way to accelerate NDC adoption, diversify indirect channel options, and reach new markets. The Travel Distribution Aggregator Market Report 2025 takes a close look at this shift. It explores how the aggregator market is developing, what airlines need to consider when shaping partnership strategies, and which technology providers are shaping the future of indirect distribution today.
