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 | Instant key on paid plans from $19 + 1,000-request free trial Self-serve |
| Pricing | Enterprise / negotiated | Transparent plans from $19 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 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 1,000-request monthly free trial, self-serve paid plans from $19 with an instant API key, 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.
Amadeus vs SkyLink API: common questions
Amadeus offers a broad travel and GDS platform with extensive enterprise APIs. SkyLink is focused, developer-first aviation data: true ADS-B, decoded weather, airports, navaids, charts and ML predictions, self-serve plans from $19 plus a free trial.
Free access — Amadeus: Test environment, complex onboarding; SkyLink API: Instant key on paid plans from $19 + 1,000-request free trial. Every SkyLink plan includes all data endpoints and paid plans include a commercial licence.
Amadeus: Not a core focus. 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.
