Feature comparison
Amadeus vs SkyLink API at a glance
An enterprise travel platform versus a focused, real-time aviation data API.
| Feature | Amadeus | SkyLink API |
|---|---|---|
| Free / self-serve access | Test environment, complex onboarding | 1,000 requests / month, instant Self-serve |
| Pricing | Enterprise / negotiated | Transparent plans from $18.59 Transparent |
| Real-time ADS-B tracking | Not a core focus | Yes — ADS-B, ~5 s updates |
| METAR / TAF weather | Not a core focus | Yes — decoded, US & international |
| Airport / navaid database | Reference data within travel APIs | Full ICAO/IATA, runways, navaids & frequencies |
| Aerodrome charts | Not available | SID/STAR/approach across 91 countries |
| ML flight-time & FAA delays | Not available | ML flight-time + live FAA delay status (US) |
| MCP server for AI | Not available | Yes — native MCP server |
| Integration effort | Higher — enterprise contracts | Low — one key, REST + SDKs |
| Uptime SLA | Enterprise agreements | 99.9% published |
Amadeus capabilities per public developer documentation; it serves broad travel/GDS use cases beyond this comparison. Verify current details with the provider. SkyLink FAA delay status is US-only.
Beyond flight status
Where SkyLink API goes further
For real-time aviation data specifically, SkyLink is purpose-built — no enterprise onboarding required.
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 teams move
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 Amadeus does not offer at all.
Aviation data without the enterprise overhead
True ADS-B, weather, charts and ML predictions — self-serve from a free tier, one API key.
