AWS published a sample airline voice-agent architecture linking Nova 2.5 Sonic, Bedrock AgentCore, backend tools, and policy documents.
AWS published a technical guide on October 6, 2026, showing how to add a voice-based travel concierge to an airline application. The sample combines Amazon Nova 2.5 Sonic for real-time speech, Amazon Bedrock AgentCore to host and connect the agent, and Bedrock Knowledge Bases to ground policy answers in airline documents.
In the example, travelers can ask about itineraries, seat assignments, flight status, meal preferences, and airline policies by speaking. They can also request a handoff to a live agent. The concierge is designed to sit alongside an airline’s existing app screens, allowing users to switch between voice and touch within the same session. AWS notes that the demo connects to a sample backend populated with synthetic data, rather than a live airline’s booking systems.
The architecture uses the Strands Agents framework and the Model Context Protocol (MCP) to expose backend functions as tools. AgentCore Gateway passes those requests to REST endpoints, where AWS Lambda handles tasks and Amazon DynamoDB stores sample booking and passenger information. Nova 2.5 Sonic streams audio through a WebSocket connection and can call tools asynchronously, allowing the conversation to continue while data is retrieved.
For policy questions, Bedrock Knowledge Bases retrieves relevant passages from airline documents and supplies them to the agent as citations. The post’s example includes materials covering baggage, cancellations and refunds, rebooking, pet travel, loyalty terms, and upgrades. AWS says the sample asks travelers to confirm before changes are written to the backend. It also recommends adding Bedrock Guardrails in production to help filter prompt-injection attempts and check response grounding.
AWS provides the solution as a modular build deployed with the AWS Cloud Development Kit. Its components include authentication through Amazon Cognito, a React front end hosted on AWS Amplify, and monitoring through CloudWatch. The guide is aimed at developers adapting the demonstrated pattern to their own airline services; it does not announce a deployment by an airline or a new AWS product release.
