In travel, latency kills conversion. When search results take more than a few seconds, users abandon, and every abandoned search costs money.
Estea’s Travel Cache Engine is built specifically for high-volume travel platforms. It delivers sub-second search responses, protects supplier rate limits, and dramatically reduces the cost of live API hits, allowing you to scale traffic without scaling operational overhead.
This is not a generic cache. It is a travel-specific performance layer designed for real-world booking complexity.
The Travel Cache Engine acts as the performance backbone across the Estea ecosystem:
The cache is not a standalone box, it is the layer that makes every other product usable at scale.
Real-Time Availability Integrity
Speed is meaningless if prices fail at booking.
The Travel Cache Engine balances performance with accuracy by intelligently refreshing data based on demand patterns and booking risk. High-velocity routes and inventory are refreshed aggressively, while lower-risk data is cached longer, ensuring users see prices that are actually bookable and protecting your look-to-book ratios.
The result: fast search responses without false availability or failed confirmations.
Supports: AI Booking Engine, Curated Packaging, and B2B/B2C booking flows
API Cost & Rate-Limit Shielding: Every live search request to a GDS or supplier costs money, or consumes limited rate quotas. The Cache Engine absorbs high-frequency and repetitive searches, serving results from high-speed memory instead of repeatedly hitting third-party APIs. This allows you to:
•Handle traffic spikes and seasonal demand safely
•Reduce supplier API costs
•Protect rate limits during bot traffic or marketing surges
•Your suppliers see fewer unnecessary hits.
•Your infrastructure stays stable.
•Your costs stay predictable.
•Integrated seamlessly with your API Distribution layer
Unified, Multi-Product Search Acceleration
•Travel platforms rarely serve a single product.
•The Travel Cache Engine normalizes and accelerates search across:
•Directly contracted inventory
•GDS and NDC airline content
•Hotel and transfer suppliers
•Curated and dynamic packages
•Whether a user is searching for a simple hotel stay or a multi-component journey, the cache delivers a single, high-speed response layer, regardless of how many underlying systems are involved.
•This architecture scales cleanly as inventory grows into tens of millions of data points.
•OTAs handling large-scale search traffic
•TMCs and B2B platforms with partner-facing APIs
•Travel platforms struggling with API costs and latency
•Engineering teams optimizing for performance and reliability
Will cached prices be out of date?
No. Cache refresh behavior is configurable. High-demand inventory can refresh frequently, while stable data is cached longer, ensuring an optimal balance between speed, accuracy, and cost.
Does this replace my supplier APIs or GDS connections?
No. The cache complements supplier APIs. It reduces unnecessary calls and only fetches live data when needed, making your platform faster and significantly cheaper to operate.
Can this handle millions of concurrent users?
Yes. The Travel Cache Engine is designed for high-concurrency travel environments and peak-season traffic, preventing slowdowns or crashes during heavy demand.
