Flight Sweep

A two-phase pipeline for comprehensive flight analysis:

1. Collect (flight_sweep_collect.py) -- Fetches flight data from Google Flights and Duffel API across multiple departure dates and trip configurations. Caches raw API responses to disk.
2. Analyze (flight_sweep_analyze.py) -- Reads cached data, applies constraint filters, builds trip scenarios, scores and ranks them, and generates an interactive HTML viewer.

When to use

Use this skill when the user wants to do a broad search across multiple departure dates and trip duration options, compare strategies, and generate a comprehensive ranked report.

Phase 1: Data Collection

DUFFEL_API_KEY=<your-key> python3 ${CLAUDE_PLUGIN_ROOT}/scripts/flight_sweep_collect.py

What it does:

• Iterates over configured departure dates (Fridays and Saturdays)
• For each date, calculates leg dates for all combinations of Europe nights (21/22/23) and India nights (5/6/7)
• Searches both one-way flights (Google Flights + Duffel) and round-trip flights (Duffel only)
• Caches each API response as a JSON file in flight_cache/
• Skips already-cached searches for incremental re-runs
• Rate-limits Duffel requests (0.5s delay between calls)

Cache format: {source}_{origin}_{dest}_{date}[_rt_{return_date}].json

Phase 2: Analysis

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/flight_sweep_analyze.py

What it does:

• Reads all cached flight data from flight_cache/
• Applies constraint filters:
• Max 1 stop per leg
• Max 4-hour layover
• Single carrier per leg
• Excludes test/synthetic airlines (e.g., "Duffel Airways")
• Builds scenarios for both strategies (3 one-ways, 2 round-trips)
• Scores each scenario: flight_cost + (hours * $20) + (stops * $200) + (weekdays * $200)
• Prints top 10 results to terminal
• Generates flight_sweep_viewer.html -- an interactive DataTables-powered HTML viewer with sorting and filtering
• Saves full results to flight_sweep_results.json

Configuration

Both scripts share these configurable constants:

Environment variables

Dependencies

• requests (pip install requests) -- Duffel API calls
• fast-flights (pip install fast-flights) -- Optional Google Flights scraper
