cheapest_dates
ChatGPTTripuck price calendar — for a given route, returns the cheapest daily price across a full month. Use this when the user shows date flexibility: "when is the cheapest day to fly IST-AYT in April?", "hangi gün daha ucuz?", "أرخص يوم للسفر", "günstigste Tage für...".

All widget UI text and the text response are then returned in that language.
