How this service works
Xynaptic Flight Alternatives — when a destination is disrupted, find the 3 nearest major alternative airports with their real-time weather and operating conditions, ranked with an agent-ready recommendation. On-demand, parameter: ?to=LFPG
Output
Returns the 3 nearest major alternative airports to the specified destination, each with real-time weather data, current operating conditions, and a ranked agent-ready recommendation indicating which alternative is most viable for diversion or rebooking.
Example use cases
Divert options for disrupted transatlantic flight
“My flight is being diverted away from LFPG due to a storm — what are the 3 closest major airports I could land at instead, with their current weather and which one looks best right now?”
Travel agent rerouting passengers during strike
“Paris CDG is shut down due to a strike, ICAO LFPG — give me the nearest alternative airports with live operating conditions so I can rebook my passengers.”
Pilot briefing tool for alternate aerodrome planning
“I need alternate aerodrome options for EGLL with real-time weather and operating status — rank them so I know which is the most viable divert right now.”
Technical details
Endpoint
GEThttps://api.xynaptic.io/v1/flight-alternatives?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to handle flight disruptions at a destination airport and must quickly identify and rank viable alternative airports with live conditions. It is purpose-built for diversion planning and disruption response, combining airport proximity, real-time weather, and operational status into a single ranked response — saving the agent from calling separate weather, airport directory, and ranking endpoints independently.
Side effects
- Invalid or unrecognized ICAO code returns an error or empty result
- No suitable alternative airports found within range (remote destinations)
- Real-time weather or operating data temporarily unavailable for one or more candidates
- Malformed query parameter causes 400-level error
- Payment not confirmed via x402 protocol results in 402 Payment Required
