You are an expert travel technology consultant with a deep understanding of flight pricing algorithms, API integrations, and user interface design for travel booking platforms. Your task is to create a detailed product requirements document for a "Last-Minute Flight Deal Aggregator" application. This aggregator will scrape and combine flight data from various sources to present users with the best last-minute deals. Product Overview: * Name: Last-Minute Flight Deal Aggregator * Description: A web and mobile application that aggregates last-minute flight deals from multiple sources, allowing users to easily find and book affordable flights. * Target Audience: Budget-conscious travelers, spontaneous travelers, and individuals with flexible travel dates. Document Structure: Please structure the document into the following sections. Use plain text sections, not markdown. 1. Goals and Objectives: * Clearly define the primary goals of the application (e.g., increase flight bookings, provide a user-friendly experience, offer competitive pricing). * Specify measurable objectives for the first 6 months of operation (e.g., achieve X number of users, generate Y revenue, attain a Z star rating in app stores). 2. Functional Requirements: * Data Aggregation: * Specify data sources (e.g., Skyscanner API, Kiwi.com API, direct partnerships with airlines). * Describe the data scraping and aggregation process, including error handling and data validation. * Define the frequency of data updates (e.g., every hour, every 15 minutes). * Search and Filtering: * List the available search criteria (e.g., departure city, arrival city, date range, budget). * Describe the filtering options (e.g., number of stops, airline, flight duration). * Deal Ranking and Presentation: * Explain the algorithm for ranking deals (e.g., price, flight duration, number of stops). * Describe how deals are presented to the user (e.g., clear display of price, flight times, airline, and booking link). * Booking Integration: * Outline the process for redirecting users to the airline or online travel agency (OTA) website for booking. * Specify any affiliate tracking or commission structures. * User Account Management: * Describe the user registration and login process. * List the features available to registered users (e.g., save favorite routes, set price alerts, view booking history). * Alerts and Notifications: * Explain how users can set up price alerts for specific routes. * Describe the notification system for sending alerts (e.g., email, push notifications). 3. Non-Functional Requirements: * Performance: * Specify the desired response time for search queries (e.g., less than 3 seconds). * Define the maximum number of concurrent users the application should support. * Scalability: * Describe how the application can be scaled to handle increasing traffic and data volume. * Security: * Outline the security measures to protect user data and prevent fraud (e.g., SSL encryption, secure password storage). * Usability: * Describe the desired user experience (e.g., intuitive interface, easy navigation, clear and concise information). * Mention any accessibility considerations (e.g., compliance with WCAG guidelines). * Maintainability: * Describe how the application can be easily maintained and updated. 4. UI/UX Design Considerations: * Provide guidance on the overall look and feel of the application. * Describe the key UI elements and their functionality. * Emphasize the importance of a mobile-first design. 5. API Integrations: * List the APIs that need to be integrated (e.g., Skyscanner API, Kiwi.com API). * Describe the data exchange format (e.g., JSON). * Outline the authentication and authorization mechanisms. 6. Future Enhancements: * Suggest potential future features (e.g., integration with hotel booking platforms, car rental services, travel insurance). * Describe how the application can be adapted to support new data sources and technologies. 7. Assumptions and Constraints: * List any assumptions made during the requirements gathering process (e.g., availability of reliable APIs, sufficient funding). * Identify any constraints that may impact the development of the application (e.g., budget limitations, regulatory requirements). Tone and Style: * The tone should be professional, clear, and concise. * Use precise language and avoid ambiguity. * Provide specific details and examples.
