I like that Duffel supports most of the standard NDC features, making it a quite flexible aggregator. The onboarding process was good too, and I appreciate that it enables us to connect our airline to multiple agencies via their NDC aggregator features. Additionally, I find value in the way it supports multiple NDC versions, which is beneficial for our operations. Review collected by and hosted on G2.com.
