CACHE-FIRST SEARCH. LESS CALLS.
MORE MARGIN.

In travel, latency kills conversion. Every extra second costs bookings. Estea's Travel Cache Engine delivers fast search responses, protects supplier rate limits (L2B), and reduces the cost of live API hits.

The Performance Layer

LATENCY IS A
REVENUE PROBLEM.

Slow search is not a UX issue. It is a direct conversion drag. Every second of added latency in the booking funnel costs abandoned searches, lost revenue, and damaged brand trust.

Most travel platforms hit live GDS and supplier APIs on every search request. Each call takes time and costs money - and when more users search simultaneously, that cost multiplies. During peak booking windows or marketing surges, the system slows down precisely when it needs to perform best.

Estea's Travel Cache Engine sits between your search layer and your suppliers. High-frequency and search requests are served from high-speed cache instead of firing live API calls for every search. Suppliers see only the requests that genuinely require a live hit.

This is not a generic caching layer. It is a travel-specific performance system designed around the real complexity of bookings: dynamic pricing, allotment windows, route volatility, and look-to-book ratios - built to stay accurate while staying fast.

Accuracy Architecture

SPEED IS MEANINGLESS IF
PRICES FAIL AT BOOKING.

Most cache implementations trade accuracy for speed. Estea's cache is built for updating live prices in real time so that cache never has stale prices that get rejected at booking.

◆
Demand-Driven Refresh Intelligence
All or defined routes and inventory are refreshed aggressively. The engine continuously adapts refresh behaviour based on demand patterns and booking risk, ensuring prices are always bookable.
Dynamic Refresh Strategy
○
Look-to-Book Ratio Protection
False availability destroys look-to-book ratios and supplier relationships. The cache layer is tuned to protect booking confirmation rates - not just search speed. No fast searches that fail at checkout.
Confirmation Rate Optimised
⚡
Peak Season Scaling
Built for high-concurrency travel environments. During peak booking windows - holidays, sale events, marketing surges - the cache layer performs despite the volume spike without degrading search performance or destabilising supplier connections.
Horizontal Scale at Peak
🔒
Supplier Rate-Limit Shielding
Every live GDS or supplier API call consumes quota. Bot traffic, marketing surges, and repetitive searches can exhaust rate limits fast. The cache absorbs these hits, protecting your supplier relationships and API cost ceilings.
API Cost Control
■
Multi-Product Normalisation
The cache normalises and accelerates search across directly contracted inventory, GDS content, hotel suppliers, transfers, and curated packages - delivering a single high-speed response regardless of how many systems are involved.
Unified Search Acceleration
◇
Configurable Cache Behaviour
Cache refresh frequency, TTL windows, and hot-route prioritisation are all configurable. High-demand inventory can refresh more often. Stable, lower-risk data can be cached longer. Full control without manual monitoring overhead.

Cost and Margin Protection

SCALE TRAFFIC.
NOT SUPPLIER COSTS.

The cache layer is as much a commercial tool as it is a technical one. Every hit absorbed is a cost saved and a supplier relationship protected.

▶
API Cost Reduction
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 them from memory instead of re-hitting third-party APIs.
  • →Handle traffic spikes and seasonal demand safely
  • →Reduce GDS and supplier API costs significantly
  • →Protect rate limits during bot traffic and marketing surges
  • →Predictable infrastructure costs even as search volume scales
🔒
Supplier Relationship Protection
Suppliers don't just charge per call - they enforce rate limits. Exceeding them can result in throttled access, degraded terms or penalties. The cache layer keeps your call volume clean and your supplier relationships intact.
  • →Suppliers see fewer unnecessary and duplicate hits
  • →Infrastructure stays stable during peak demand windows
  • →Rate limit breaches prevented before they happen
  • →Cleaner call patterns improve supplier commercial terms over time
Platform Role

THE BACKBONE THAT MAKES
EVERY PRODUCT USABLE AT SCALE.

The Cache Engine is not a standalone product. It is the performance infrastructure that enables every other Estea solution to operate at production speed.

◆
AI Booking Engine
Enables instant conversational responses without thinking delays. When Estea AI Booking Engine surfaces a recommendation, the inventory data behind it is already pre-fetched and ready - no perceptible lag between intent and result.
○
API Distribution
Allows sub-agents and partners to receive fast API responses. Without the cache, every partner search would fire a live supplier hit. With it, hundreds of concurrent partner calls are served without additional cost.
◇
Curated Packaging
Makes multi-component package assembly feel real-time. Assembling a flight, hotel, and transfers from three supplier sources in under 2 sec is only possible because each component is already cached and ready to be assembled dynamically.
FAQ

FREQUENTLY ASKED
QUESTIONS

Common questions about Estea's Travel Cache Engine.

No. Cache refresh behaviour is configurable per inventory type and in real-time. High-demand inventory refreshes frequently. Stable data is cached longer. The engine balances speed, accuracy, and cost - and is specifically designed to protect booking confirmation rates, not just search speed.

No. The cache complements supplier APIs - it reduces unnecessary calls and only fetches live data when genuinely needed. Your existing GDS and supplier integrations stay in place. The cache sits in front of them as a performance and cost layer.

Yes. The Travel Cache Engine is designed for high-concurrency travel environments and peak-season traffic. Horizontal scaling means capacity grows with demand without manual infrastructure changes or performance degradation during heavy load.

Direct-contracted inventory is synced in real time between the Direct Contracting platform and the cache layer. Stop-sales and allotment changes propagate immediately - cached data never becomes a source of false availability for private contracts.

The cache engine is a separate module that integrates with your existing booking engine and supplier stack as part of the Estea platform. It does not require replacing existing infrastructure - it operates as a performance layer on top of what you already have.
