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.
FL3XX is the scheduling system used by hundreds of charter operators. Its external API exposes every empty leg an operator publishes — route, aircraft, tail number and dates. Access is arranged per-operator through FL3XX.
Leon is the other major operator scheduling platform. Operators can distribute their availability and empty legs to partner marketplaces directly from Leon add-ons, syncing automatically.
Aggregates empty legs by syncing with operators' scheduling systems (Leon, FL3XX and calendar feeds) every few minutes. A single integration point for many operators at once.
A free, continuously refreshed feed of discounted empty-leg flights, syndicated in exchange for a credit link. It is wired into our importer and runs on demand from the admin console: new legs are added, existing legs updated, and legs that disappear from the feed are retired automatically.
