Building a Travel Aggregator Platform: Technical Architecture

Travel aggregators like Kayak and Skyscanner search dozens of sources simultaneously to find the best prices. Building one requires sophisticated caching, parallel API calls, and intelligent result deduplication.

Architecture Challenges

• Parallel Search: Query 20+ suppliers simultaneously with timeout management.
• Result Normalization: Map different data formats into a unified schema.
• Deduplication: Identify the same flight/hotel across different sources.
• Caching Strategy: Balance freshness with performance using tiered caching.
