Flight Deal Radar

A small MVP that searches for affordable Thursday-to-Sunday weekend flights from NRW and nearby low-cost airports by querying public, keyless airline website endpoints and displays them in a Next.js 16 application.

What it checks

• Origins: CGN, NRN (Weeze), DUS, DTM, PAD plus nearby alternatives FRA, HHN, EIN, BRU, CRL
• Providers: Ryanair and Wizz Air public, keyless website endpoints
• Destinations: a broad fallback set of European leisure spots, plus dynamically discovered Ryanair routes where available
• Trip pattern: Thursday departure, Sunday return
• Search window: next 8 weeks
• Deal threshold: flights up to 160 EUR

Data source

The scanner uses public, keyless website endpoints from Ryanair and Wizz Air. No API keys or GitHub Secrets are required — the old Amadeus integration has been removed.

Ryanair routes are discovered dynamically from its public route index and merged with a maintained fallback destination list. Destinations or airports that a provider does not serve simply return no results. The scanner uses a normal browser-like user agent and a small delay between requests so it remains suitable for private, personal deal checks.

Run the flight scanner locally

python -m pip install -r requirements.txt
python src/check_flights.py

The scanner writes matching offers to data/deals.json.

Run the Next.js app locally

npm install
npm run dev

Open http://localhost:3000 to view the deal radar. The Next.js app reads data/deals.json on the server and renders the current deal cards.
