How Avelo Airlines Future-Proofed Its Application Infrastructure with Dapr

From day one, Avelo Airlines has been guided by a mission to Inspire Travel and a commitment to core values like Safety Always, Keep It Simple, Do the Right Thing, and One Crew. These principles shaped every decision as the airline built a modern, resilient IT infrastructure from the ground up.

Building a Future-Ready Foundation

When Avelo Airlines launched in April 2021—the first new U.S. airline in nearly 15 years—it faced the rare opportunity and challenge of building its IT systems from scratch. Determined to avoid the pitfalls of legacy systems, Avelo's leadership partnered with Hynes & Khater to execute a bold IT vision.

The core requirements for Avelo's technology stack included:

• Cloud-first, cloud-native architecture to avoid costly and rigid data center investments.
• Scalability and flexibility to support growth without constant overhauls.
• Event-driven data flow for efficient, responsive operations.
• Loose coupling between systems to enable fast integrations and reduce vendor lock-in.
• Future readiness to swap out core systems without disrupting operations.

Engineering for Agility: Embracing Dapr

Hynes & Khater led the engineering team in adopting a Kubernetes-based, API-centric architecture deployed on Microsoft Azure. A standout decision was the adoption of Dapr to power an event-driven, pub-sub messaging architecture.

Key Benefits:

• Simplified integrations: Dapr's sidecar model enabled seamless message handling without complex middleware.
• Standardized communication: Over 76 core APIs—from reservations to HR—were unified under a clean, consistent messaging layer.
