Airline IT failures are more common than many travelers realize, leading to delays, cancellations, and frustration. Despite advances in technology, airlines still face significant challenges in maintaining reliable systems. Curious about what causes these outages and what’s being done to prevent them? Below, we explore the main reasons behind airline tech failures and how the industry is working to improve system resilience.
-
What causes airline IT system failures?
Airline IT failures often stem from hardware issues, software bugs, or cyberattacks. Complex systems that manage bookings, check-ins, and flight operations are vulnerable to hardware failures, outdated software, or cyber threats. Recent outages, like Alaska Airlines' system disruptions, highlight how hardware failures and system overloads can cause widespread issues.

What are some recent major airline outages?
One notable recent outage was Alaska Airlines' second IT failure within months, which caused a ground stop and flight cancellations affecting over 400 flights. Hawaiian Airlines was unaffected, showing that outages can be specific to certain airline systems. These incidents underscore ongoing vulnerabilities in airline IT infrastructure.
-
How are airlines improving their tech resilience?
Airlines are investing in better infrastructure, bringing in external experts, and upgrading their systems to prevent outages. Alaska Airlines, for example, has hired specialists to diagnose and strengthen its systems after recent failures. Industry-wide, airlines are adopting more robust backup systems and real-time monitoring to reduce downtime.
-
What should travelers know about airline system reliability?
Travelers should be aware that system failures can happen unexpectedly, leading to delays or cancellations. It's wise to check flight statuses before heading to the airport and stay updated through airline apps or customer service. Despite improvements, no system is completely foolproof, so flexibility and patience are key.
-
Are airline outages increasing or decreasing?
While technology has advanced, airline outages still occur regularly, partly due to increasing system complexity and cyber threats. Recent incidents suggest that outages are still a significant challenge, prompting airlines to focus more on resilience and cybersecurity measures.
-
What is being done industry-wide to prevent future outages?
The airline industry is working on standardizing best practices, investing in new technology, and improving cybersecurity. Regulatory bodies like the FAA also require airlines to have contingency plans. These efforts aim to reduce the frequency and impact of system failures in the future.
