I need a web-based tool that produces complete travel itineraries for both flights and hotels in one flow. The core requirement is real-time booking integration: when a traveller selects an option, the system should pull live availability and pricing from the chosen suppliers and let them confirm the reservation without leaving the site. You are free to pick the most suitable stack—whether that is React with Node, Django, Laravel, or another framework—but the final product must: • Accept basic trip parameters (origin, destination, dates, number of travellers). • Query reputable flight and hotel APIs, then present ranked options clearly. • Combine the selected items into a single, printable / shareable itinerary page. • Complete the booking through API endpoints or affiliate links and return confirmation details. • Include an admin area where I can add or swap suppliers and set markup rules. A clean, responsive UX is important because the app will be used on both desktop and mobile browsers. Future phases may expand into user profiles or deeper customisation, so write modular code and keep the architecture extensible. Please outline the APIs you recommend, any licence or key costs I should expect, and a rough milestone plan from prototype to launch. Once delivered, I will test with a live key before final sign-off.
