## At a glance

可以用于背景和历史模式，但当天旅客决策应以 SEA 机场和航空公司状态为准。

## 完整指南

OpenSky Network 提供免费的 ADS-B 航班数据，按 KSEA 机场代码记录历史抵达与出发；但数据为后台批量延迟更新，不适用于当天即时航班追踪。当天旅客决策应以西雅图港官方航班屏及航空公司订单为准。开放数据能为规划提供有价值的宏观规律，例如识别清晨（5:00-8:30）、午间（10:00-14:00）或傍晚（18:00-21:00）的 3 大客流高峰期，辅助预测租车中心大巴及柜台的排队时长。在开发产品时，应结合官方实时源和开放历史规律指导出行。

### At a glance

Yes for context and historical patterns, but same-day traveler decisions should use SEA Airport and airline status.

### Compare

OpenSky API vs. Port of Seattle FIDS: OpenSky provides raw ADS-B telemetry, aircraft registration details, and historical flight logs, making it ideal for predictive analytics and macro trend charts. In contrast, the Port of Seattle FIDS is directly connected to the airport's terminal database (powered by SITA or Amadeus systems receiving updates from gate agents and ACARS) and represents the authoritative source for live gate changes, baggage carousels, and delay statuses.

ADS-B Telemetry vs. ACARS Logs: ACARS (Aircraft Communications Addressing and Reporting System) logs four discrete OOOI events: Out of gate, Off ground, On ground, and Into gate. OpenSky only captures physical takeoff and landing times. Discrepancies occur when a plane lands but waits 20 minutes on the taxiway for an open gate; OpenSky logs this as 'landed' while the passenger remains stuck on the tarmac, which is why ACARS or live airport status is required for same-day action.

### Honest heads-up

Public Rate Limiting: The OpenSky REST API enforces strict rate limits to prevent server abuse. Anonymous users are limited to 300 API requests per day, while registered users receive 1,200 requests. High-traffic applications must run local caching proxy layers or run their own ADS-B receiver hardware to bypass these limitations.

Missing Data Vectors: Because OpenSky relies on volunteer-run receiver stations, coverage gaps can occur, especially for low-altitude aircraft or flights approaching from mountainous regions in Washington state, leading to missing arrivals in the database.
