NDC Exchange API

Developed and hosted by SITA and ATPCO, NDC Exchange is a community-driven marketplace for airlines and travel sellers who want to create offers and distribute them directly to customers.

What makes NDC Exchange different? NDC Exchange translates messages from any API or schema they are based on. Whether you are an airline or travel seller using a pre-NDC API (OTA & Open Axis) or you are still developing your API, the exchange has you covered.
