AirLabs vs SkyLink API at a glance
Aggregated flight and schedule data versus a unified real-time aviation data API.
| Feature | AirLabs | SkyLink API |
|---|---|---|
| Free tier | Limited free key | 1,000 requests / month free trial Generous |
| Entry paid plan | Subscription tiers | $19 / mo · 5,000 requests Transparent |
| Real-time flight tracking | Yes — aggregated | Yes — ADS-B, ~5 s updates |
| True ADS-B positions | Aggregated, not raw receiver data | Yes — ICAO24 hex, bounding-box queries |
| METAR / TAF weather | Not available | Yes — decoded, US & international |
| Airport / airline database | Yes — reference data | Full ICAO/IATA, runways & frequencies |
| ML flight-time & FAA delays | Not available | ML flight-time + live FAA delay status (US) |
| Aerodrome charts | Not available | SID/STAR/approach across 91 countries |
| Historical data | Limited | Up to 365 days (90 d Pro, 365 d Business) |
| Uptime SLA | Not published | 99.9% published |
AirLabs capabilities per public documentation; verify current details with the provider. SkyLink FAA delay status is US-only.
Beyond flight status
Where SkyLink API goes further
SkyLink pairs reference data with true real-time ADS-B, weather and predictions — so you don’t stitch together multiple providers.
True ADS-B, ~5-second updates
SkyLink reads raw ADS-B receiver data — ICAO24 hex, callsign, latitude, longitude, altitude, ground speed and track — sampled roughly every 5 seconds, with bounding-box queries for any map viewport.
Decoded METAR & TAF weather
Fully decoded METAR observations and TAF forecasts across US and international airfields — wind, QNH, visibility, cloud layers, temperature and dew point — alongside live flight data.
Complete airport & navaid database
Search 74,000+ airports by ICAO, IATA, city, location or IP, with runways, frequencies, navaids (VOR, NDB, ILS) and elevation.
ML flight-time, FAA delays & carbon
An ML gate-to-gate flight-time model, a real-time FAA delay-status feed, and ICAO-based carbon estimates — all behind one key.

Production-grade reliability
99.9% uptime SLA, region-local endpoints and sub-second responses — built for apps that can’t afford downtime.
One API key
The whole aviation stack
Everything below ships under a single SkyLink key - most of it AirLabs does not offer at all.
AirLabs vs SkyLink API: common questions
AirLabs provides flight, schedule and airline reference data through an aggregated API. SkyLink adds a true ADS-B receiver network, decoded weather, navaids, charts and ML predictions — with a 99.9% uptime SLA behind one key.
AirLabs: Subscription tiers. SkyLink API: $19 / mo · 5,000 requests. Free access — AirLabs: Limited free key; SkyLink API: 1,000 requests / month free trial. Every SkyLink plan includes all data endpoints and paid plans include a commercial licence.
AirLabs: Aggregated, not raw receiver data. SkyLink API: Yes — ICAO24 hex, bounding-box queries, refreshed roughly every 5 seconds.
AirLabs: Not available. SkyLink API: Yes — decoded, US & international, on the same API key as flight data.
Get an API key, run SkyLink alongside your current provider while you map response fields using the API reference, then move traffic over. Official SDKs for Python, Node.js and Go keep the change small, and paid plans include a key immediately after checkout.
