A tiny macOS menu bar app that shows your flight's live altitude and telemetry when you're connected to in-flight Wi-Fi.

Note: this project was written almost entirely by an AI coding agent (Claude). Treat the code accordingly — read before you trust it.

• Delta Air Lines — any SSID containing deltawifi

Want another carrier? See Adding another airline below — it's one file.

• Lives in the menu bar; no Dock icon.
• Auto-detects in-flight Wi-Fi by SSID and talks to the airline's captive-portal API for live flight data.
• Currently supports Delta (any SSID containing deltawifi). Architecture is pluggable — adding a new carrier is one AirlineProvider conformance.
• Click the menu bar item for a popover with altitude, airspeed, ground speed, heading, outside temperature, route, time remaining, phase, and flight number.
• Customizable:
  • Which fields appear in the menu bar label (and their order).
  • Refresh interval (1s / 3s / 5s / 10s / 15s / 30s / 60s, default 5s).
  • Imperial (ft · kt · °F) or metric (m · km/h · °C) units.
• Shows a warning icon when the airline reports connectivity is down.

• macOS 13 Ventura or later.
• Location permission — macOS 14+ gates Wi-Fi SSID access behind Location Services. Airwatch asks for it the first time it launches.

Open Airwatch.xcodeproj in Xcode and hit Run, or:

xcodebuild -project Airwatch.xcodeproj -scheme Airwatch -configuration Release build

The same sources also build as a Swift Package:

swift build

(The SPM target runs as a plain executable without a proper app bundle — use the Xcode project for day-to-day use.)

1. Create Sources/Airwatch/Providers/<Airline>/<Airline>Provider.swift conforming to AirlineProvider:
   • matches(ssid:) — identify the carrier's in-flight Wi-Fi.
   • fetchSnapshot() — hit the captive-portal API and return a normalized FlightSnapshot.
2. Register it in ProviderRegistry.default.
3. That's it — the UI, preferences, and formatting all work automatically.

Pushing a tag matching v* (e.g. v0.1.0) triggers a GitHub Actions workflow that builds the app and publishes a zipped Airwatch.app as a GitHub release asset. The build is unsigned and ad-hoc codesigned — you'll need to right-click → Open the first time, or remove the quarantine attribute:

xattr -dr com.apple.quarantine /Applications/Airwatch.app
