About Adtouch Labs

Adtouch Labs is a product and engineering company specializing in software infrastructure for the travel and hospitality.

Voice AI for Tours & Activities

Our newest platform, the Voice AI system handles calls, answers questions and checks live availability via the merchant API, and sends booking links by text. Tour companies can now capture every lead automatically — improving customer response time while eliminating the need for overnight staff or missed calls — with little to no effort to implement.

Impact

Automated call handling and routing, zero missed leads, and eliminated need for overnight staff while maintaining 24/7 availability.

OpenAI + n8n + Zendesk Integration

We built an AI-assisted workflow that combines OpenAI language models, n8n automation, and Zendesk. It analyzes hotel and profile data to draft accurate, context-aware replies for United's support agents — reducing manual lookup and improving response quality. By automating data retrieval and reply generation, response times dropped significantly and teams were able to manage higher volumes with less effort.

Impact

Significantly reduced response times and enabled support teams to handle higher ticket volumes with improved accuracy.

United Airlines — MileagePlus X App

We designed and continue to operate the MileagePlus X mobile platform, which powers the MileagePlus program through a single user experience. The app connects shopping, dining, hotel, and eGift rewards under one API-driven system.

Impact

Consolidated multiple reward programs into one unified platform that's easier to maintain, faster to scale, and more consistent across millions of users.

United Airlines — Loyalty SDK

Our Loyalty SDK provides United's internal developers with a consistent framework to publish and manage offers inside the United app without waiting for new releases.

Impact

United gained the ability to launch new promotions in hours instead of weeks or months — accelerating marketing velocity while lowering engineering costs.

United Airlines — Middle Layer

Behind the MileagePlus app sits a custom-built middle layer that unified United's internal APIs with data from multiple third-party providers including Marriott, Visa, eGift, surveys, shopping, dining, and hotel networks. Before this system, every front-end interface had to separately handle caching, normalization, and custom logic for each data source — creating significant operational and technical overhead.

Impact

United can now deliver consistent, normalized data to every UI, reducing redundant code, API load, and long-term maintenance cost.

United Airlines — Rakuten MileagePlus Transfer Site

We designed and operate the Rakuten MileagePlus transfer site where users can convert their MileagePlus miles to Rakuten points for shopping. The site seamlessly supports both Japanese and English while walking the user through the transfer process by integrating both United Airline's services and Rakuten's account tools.

Impact

Seamless bilingual experience connecting two major loyalty programs with streamlined user flows.

HMSHost — Digital Voucher SDK

We built a mobile SDK that lets airline passengers redeem digital vouchers through airline app QR codes at HMSHost's airport restaurants. This digital infrastructure replaced manual paper workflows, reducing fraud risk with improved reconciliation, while connecting billions of airline miles with thousands of airport restaurant cash registers.

Impact

Eliminated paper vouchers, reduced fraud, improved reconciliation, and connected airline loyalty programs to airport restaurants at scale.

Priceline + booking.com — Last-Minute Hotel Deals

We partnered with Priceline and booking.com to build a unified hotel booking flow for MileagePlus members. The architecture aggregates multiple supplier APIs into a single endpoint and reduced the user process from 12 steps to one streamlined transaction.

Impact

Improved conversion rates while lowering customer support and data synchronization workloads through simplified booking flow.
