Amadeus GDS Integration for a Mid-Size UK Travel Agency
From Manual Chaos to Real-Time Bookings in 10 Weeks
Problem Statement
Key Pain Points
- Agents switching between 3 separate tools to complete a single booking, adding 15 to 20 minutes per transaction.
- No real-time connection to Amadeus inventory, causing availability mismatches at the point of confirmation.
- PNR data is entered manually into a CRM, leading to frequent errors and duplicate records.
- Amadeus API quota exhausted during peak morning traffic, returning empty results to agents.
- Two corporate clients had issued notice to switch to a competitor with a live booking portal.

The Solution
Discovery-First Integration Audit
Before writing a single line of code, our team spent two weeks mapping every step of the agency's existing booking workflow. This revealed that the agency needed more than a GDS connection. They needed a booking engine that matched how their agents actually worked, not a generic off-the-shelf interface dropped onto Amadeus.
Amadeus Self-Service API Integration
We built the core integration using Amadeus Self-Service APIs, covering live availability search, dynamic pricing, PNR creation, seat selection, ancillary add-ons, and ticketing. Every step ran through a single unified interface so agents never had to leave the platform.
CRM Middleware Layer
A custom middleware layer connected the Amadeus booking engine to the agency's existing CRM in real time. PNR data flowed automatically on booking confirmation, eliminating manual entry and the errors that came with it.
API Caching Strategy for Peak Traffic
We implemented route-level caching for the agency's highest-volume search corridors so peak morning traffic did not exhaust the Amadeus API daily quota. Search results for popular routes served from cache in under 200ms while live inventory was refreshed in the background.
Agent-Optimised Interface
The front-end interface was designed around the agency's existing workflow rather than forcing agents to learn a new process. Training time was minimal because the tool felt like a natural extension of how they already worked.
Phased Delivery with Live Testing
We delivered the integration in two phases, running parallel live testing with a small group of agents before full rollout. This meant the agency caught edge cases in a controlled environment rather than discovering them during peak season.
OneClick IT Solutions did not just build a booking portal. They engineered a fully integrated travel commerce platform designed to convert, scale, and grow with Travel Agency's business.

Project Outcomes
40% Faster Booking Transactions
Agents completed bookings in under five minutes on average after go-live, compared to over 20 minutes when they were switching between multiple tools. That time goes back to serving clients.
Zero API Quota Failures at Peak
The caching strategy eliminated the morning traffic failures entirely. Agents stayed productive throughout the day, even during the busiest windows that had previously left them stuck.
Manual PNR Entry Eliminated
All booking data flowed automatically to the CRM on confirmation. The manual step that had been generating one error in every eight bookings simply no longer existed.
Two Corporate Clients Retained
Both clients who had issued notice to leave renewed their contracts within the first month of the new platform going live. The agency did not have to win them back. The platform did it for them.
Live in 10 Weeks
From project kick-off to full agency go-live in 10 weeks, including parallel testing and agent onboarding. No six-month delays, no half-built handoffs.
First Bug-Free Peak Season
The agency's team lead described the first post-launch peak season as the most operationally smooth the agency had experienced in five years.
