Perhaps there is no other industry as competitive as the airline industry, where margins are thin and customer loyalty is hard-won. Today's passengers demand more than just a seat from A to B; they expect a seamless, personalized digital experience that travels with them. From booking the ticket to boarding the plane, every digital touchpoint is an opportunity to delight passengers.
While many airlines focus on fleet modernization and route expansion to drive profitability, your Customer Identity and Access Management (CIAM) solution is an often-overlooked engine for business growth.
A modern, cloud-based identity platform like Auth0 does more than just secure accounts; it reduces friction, drives revenue, enhances operational efficiency and leverages AI. Here is how a strategic approach to identity can deliver tangible business value for your airline.
Improving Passenger Experience and Loyalty
According to OAG (2024), 18% of passengers fly without using a Frequent Flyer (FF) account, and this metric can be as high as 35% if we consider only the Gen Z population. This represents a missed opportunity for airlines to not only foster long-term loyalty but also to capture valuable passenger data required for personalized offers and increased revenues. In research conducted by McKinsey, top-performing loyalty programs can boost revenue from passengers who redeem points by 15 to 25% annually.
Auth0 removes the friction that typically discourages travelers from joining or accessing loyalty programs. By leveraging Auth0’s Universal Login and Progressive Profiling, airlines can improve the User Experience of the sign-up flow, while capturing data incrementally without overwhelming the user. Additionally, adopting passwordless authentication (such as Passkeys or One-Time Passwords) eliminates the frustration of forgotten credentials, helping ensure passengers never lose access to their accounts. Finally, by integrating deeply with CRM and CDP systems, Auth0 enables a "360-degree view" of the traveler, transforming identity from a technical hurdle into a powerful engine for personalization and revenue growth.
Driving Operational Efficiency via Self-Service
Labor costs are the primary expense for airlines, accounting for 28% of total costs in 2025. Furthermore, according to a TNMT analysis, flight irregularities are the leading cause of negative reviews on TripAdvisor. Following cancellations, call centers and gate agents often become overwhelmed, triggering a wave of secondary disruptions. Despite these high costs and operational bottlenecks, airlines still rely heavily on manual airport staffing for check-in, customer support, and passenger services.
Airlines can reduce labor expenses and improve recovery efficiency by accelerating the adoption of self-service tools, such as automated check-in and rebooking. These services are most effective when passengers can seamlessly create accounts and access bookings via modern, more secure, passwordless features like Passkeys.
As noted previously, Auth0 helps airlines drive registration by removing sign-up friction and simplifying the login experience. By implementing features such as passwordless access, progressive profiling, and self-service credential management, Auth0 customers have reported an increase in customer conversion rates.
Securing Airline AI Agents
Airlines are deploying AI agents across critical operations from autonomous customer service bots handling rebookings during disruptions, to predictive maintenance agents accessing sensitive aircraft data, to revenue management systems dynamically adjusting pricing across global markets. These agents operate 24/7, making real-time decisions that directly impact passenger safety, experience, and airline profitability.
As AI agents gain access to passenger data, payment systems, and operational controls, robust identity management becomes essential. Each agent needs a verified identity with specific permissions. Outsourced maintenance agents must only access systems specific to the airline they are supporting, while a customer service agent requires limited passenger data access. Without proper authentication, airlines face risks of unauthorized data access, compliance violations, and potential safety incidents from compromised operational systems. According to research conducted by Amadeus, data security is the number one reason that’s preventing widespread adoption of AI in travel.
Auth0 for AI agents provides airlines with enterprise-grade security through machine-to-machine authentication, granular relationship or attribute-based access controls, and comprehensive audit trails. Airlines can more securely tie agent actions and identity to unique human identities, define precise API access scopes, and help ensure agents are strictly bound to the permitted scopes set by human users. This helps ensure AI agents operate more securely and cannot overstep the boundaries set by the human user while maintaining the agility airlines need for rapid innovation.
Putting the ‘Agent’ in Travel Agents
Consumers are increasingly turning to AI agents like ChatGPT, Claude, and Gemini to search for products, compare prices, and complete transactions. Soon, they will be doing the same with flights. Instead of navigating multiple airline websites or metasearch engines, they can simply ask "Find me a direct flight to Tokyo under $800 next month" and let the AI handle the rest.
Airlines that fail to make their inventory, pricing, and booking capabilities accessible to these third-party agents risk becoming invisible to this rapidly growing segment of travelers, ceding market share to competitors who embrace agentic commerce.
Auth0's Auth for MCP enables airlines to host more secure MCP servers that expose their booking capabilities to the agentic ecosystem. And through OAuth 2.1, airlines help ensure that 3rd-party agents can only interact with these servers when they have explicit, user-delegated permissions, maintaining complete control over every API call.
Protecting Brand Reputation with Best-in-Class Security
Airlines hold vast amounts of sensitive personal data, miles, travel credits and loyalty dollars, making them prime targets for cyberattacks. A single breach or a wave of account takeovers (ATO) can cause irreparable damage to your brand reputation and bottom line.
Auth0 provides best-in-class security features—including Attack Protection, Multi-Factor Authentication (MFA), Bot Detection, and Breached Password Detection. These tools work silently in the background to stop brute force attacks and prevent unauthorized access, helping ensure that your passengers' data (and your reputation) remain secure without adding unnecessary friction to the user experience.
Identity Is The Co-Pilot for Your Airline Digital Strategy
Your customer identity solution affects far more than just the login box. It influences your revenue, your operational costs, your customer satisfaction and helps secure your AI Agents. Auth0 and Auth0 for AI Agents provide the essential identity layer to secure the human and AI interactions, transforming identity from a technical hurdle into a strategic engine for the entire passenger journey.
