How this service works
Great-circle distance in km, miles and nautical miles between two airports, with a rough flight time estimate.
Output
Returns a JSON object containing the resolved metadata for both the origin and destination airports (IATA, ICAO, name, lat/lon, country, region, elevation, municipality, scheduled service), the great-circle distance expressed in kilometers, miles, and nautical miles, an estimated flight time based on the specified or default cruise speed (850 km/h), and a timestamp for when the data was computed.
Example use cases
Flight planning distance check
“How far is it from Los Angeles (LAX) to Tokyo Narita (NRT) in kilometers and nautical miles, and what's the estimated flight time at 850 km/h?”
Travel itinerary leg comparison
“I'm planning a trip and want to compare two legs — can you tell me the great-circle distance between Dubai (DXB) and Singapore (SIN), and also between Singapore and Sydney (SYD)?”
Aviation logistics route analysis
“What's the distance in miles and nautical miles from Chicago O'Hare (ORD) to Frankfurt (FRA), and how long would a flight take at a cruise speed of 920 km/h?”

Endpoint
GEThttps://airports-reference.x402tookit.com/airport-distance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise great-circle distance between two specific airports (by IATA, ICAO, or name) along with a flight time estimate. It is the right choice when you already know both airport identifiers and need a quick, structured distance result in multiple units. Prefer this over general geospatial distance APIs when you specifically need airport-aware lookups with aviation context (codes, scheduled service, elevation) included in the response.
Side effects
- Unknown or unresolvable airport code/name returns null airport object
- Invalid or out-of-range speedKmh value may return an error or use default
- Fuzzy name matching may resolve to wrong airport if name is ambiguous
- Missing required 'from' or 'to' query params returns a validation error
- Network timeout or service unavailability returns a 5xx error
