I want to build a web-based travel portal that lets users search, compare, and securely book flights and hotels in real time. Flights and hotels are the only services I need for this first release; car rentals may follow later, but are out of scope right now. Core objectives • Integrate reliable flight and hotel inventories through established APIs or GDS connections, handle live availability, pricing, and instant confirmation. • Design a clean, responsive interface (desktop and mobile) that walks users from search to payment without friction. • Implement secure payment processing and automatically generate e-tickets or booking vouchers. • Provide a lightweight admin dashboard so I can manage content, view bookings, and pull basic sales reports. Acceptance criteria • Flight and hotel searches return accurate results in under three seconds. • End-to-end booking flow completes successfully in a test environment with major cards and at least one digital wallet. • All major pages pass Google Lighthouse performance and accessibility audits (≥90/100). • Source code is handed over with setup instructions and brief API documentation. When you respond, please link to past travel or booking platforms you’ve built—screenshots or live URLs are ideal. A concise outline of how you would approach the API integration and payment gateway setup will help me assess the fit quickly.
