Flighty Email

A Cloudflare Worker that automatically extracts flight information from forwarded emails and posts formatted notifications to Slack.

How It Works

┌─────────────┐     ┌──────────────┐     ┌─────────────┐     ┌─────────┐
│   Email     │────▶│   Inbound    │────▶│   GPT-5.2   │────▶│  Slack  │
│  (forward)  │     │   Webhook    │     │  Extraction │     │  Post   │
└─────────────┘     └──────────────┘     └─────────────┘     └─────────┘

1. Forward a flight confirmation email to your inbound email address
2. Webhook receives the email via inbound.new (or similar service)
3. AI extracts flight details using OpenCode Zen's GPT-5.2
4. Slack notification is posted with all flight information

Features

• Extracts multiple flights from a single email (round trips, connections, etc.)
• AI-generated trip titles and descriptions
• Structured data extraction:
  • Flight numbers
  • Confirmation codes (PNR)
  • Airlines
  • Departure/arrival airports and times
  • Passenger names and seat assignments
• Beautiful Slack notifications with Block Kit formatting
• "Track Flight" buttons linking to FlightRadar24
