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 Generous |
| Entry paid plan | Subscription tiers | $18.59 / 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 Ultra, 365 d Mega) |

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.

Why developers choose SkyLink API
One API for the whole stack
ADS-B, weather, NOTAMs, airports, navaids, charts, schedules, ML predictions and an MCP server — behind a single key and one SLA. Consolidate vendors and ship faster.
Transparent, developer-first pricing
A free tier with 1,000 requests/month, self-serve paid plans from $18.59, and no sales calls or annual contracts to get started.
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.
