Inventory pipeline

Where our flights come from

Empty leg data is not openly crawlable — operators publish it into closed marketplaces and private feeds. We connect to those feeds directly. Every listing on EmptyLeg is traceable to one of the sources below, and each flight record stores its origin.

Avinode Marketplace API

Ready to connect
Global

The largest B2B charter marketplace. Offers an end-client empty leg search endpoint and an empty leg subscription feed that pushes new and updated legs to us in real time. Requires an Avinode account with an API connection enabled by their support team.
