1. AviationStack Real-Time Integration

The extension uses AviationStack's live flight endpoint (/flights?flight_iata=XX123) polled every 2 minutes via Chrome Alarms — comparing each response against the last-known flight state stored in chrome.storage.local. Any field change (status, departure gate, estimated times) triggers an immediate notification and GPT-4o analysis.

2. GPT-4o Disruption Impact Analysis

When a cancellation or significant delay is detected, GPT-4o analyzes the disruption in context of the traveler's full itinerary (if provided) — identifying affected connections, estimating new arrival times, suggesting alternative routes with connection viability scores, and generating the airline's rebooking page URL. This transforms a bare "cancelled" notification into an actionable response plan.

3. Background Monitoring Architecture

Flight monitoring runs entirely in the Chrome Service Worker background — users don't need an active browser tab or even the extension popup open. Chrome Alarms wake the Service Worker every 2 minutes to poll AviationStack, and notifications are delivered via the Chrome Notifications API regardless of browser state.

4. Client-Side Vault & Zero-Leak Credential Hygiene

User API keys and proprietary system prompts are secured inside chrome.storage.session and isolated from the host webpage scope. The extension runs strict Content Security Policy (CSP) headers and sandboxed execution contexts, preventing unauthorized third-party scripts from reading session tokens or prompt payloads.
