As cyber risks continue to threaten the safety and stability of the aviation industry, airlines are stepping up their efforts to protect both their customers and operations. At the forefront of these changes is Southwest Airlines, a leading name in the field, guided by its experienced Chief Information Security Officer (CISO), Carrie Mills. Her approach to cybersecurity not only keeps travelers safe in the air and on the ground but also sets new standards for the entire sector. This article takes a closer look at how Southwest Airlines, under Mills’ leadership, is handling today’s cyber risks, what makes aviation especially vulnerable, and the strategies that can keep the industry moving forward in a dangerous digital world.
Southwest Airlines and the Challenge of Cyber Risks
Cyber risks have become one of the greatest concerns for aviation around the globe. Airlines like Southwest Airlines manage enormous volumes of data, rely heavily on cutting-edge technology, and serve millions of passengers every year. This mix of technology, public trust, and high visibility makes airlines an attractive target for hackers and cyber criminals.
Carrie Mills, as the Chief Information Security Officer of Southwest Airlines, oversees the company’s entire approach to fighting cyber risks. According to Mills, the challenge is particularly complex for aviation companies—they aren’t just big brands, they are also part of critical infrastructure. This means a cyberattack can cause more than missed flights or lost revenue; it can disrupt national safety or even put lives at risk.
Why Aviation Faces More Than the Usual Threats
Unlike other industries, aviation must guard against both well-known risks and new kinds of attacks. Hackers may target customer information, disrupt flight schedules, or go after the technology that controls airplanes themselves. As airlines rely more on digital systems, these dangers only grow. Mills points out that this wide range of threats demands a strong focus on being ready for surprises and responding quickly when something goes wrong.
Over the years, Southwest Airlines has worked to keep up with these changing dangers. For example, it set up one of the first cybersecurity teams in the airline industry focused only on protecting the systems and technology actually used on the aircraft—especially those that keep travelers safe during flights. By focusing on these front-line defenses, Southwest Airlines has been a leader in tackling the unique risks that come with being in the air.
New Technologies Bring New Risks—and New Defenses
The aviation world is moving fast, with airlines now using technologies like satellite-based communications, cloud systems, and artificial intelligence (AI) to keep up with demand and deliver better service. These advances bring new conveniences but also open up new ways for cyber criminals to attack.
- Satellite and Cloud Systems: Using satellite-based communications keeps planes connected no matter where they are flying. Cloud solutions help store and process huge amounts of data. But these systems mean airlines must now depend on many outside partners—each with their own risks and weaknesses. Mills stresses that security is now a shared responsibility, involving vendors, third parties, and airline staff alike.
-
Artificial Intelligence: AI tools can make it easier to spot a cyberattack quickly by sorting through large amounts of data in real time. Mills believes AI can help respond to incidents faster by giving human analysts quick, clear information. But with these gains, new dangers also appear: hackers may find ways to trick AI or use it for their own attacks.
The challenge for Southwest Airlines and its Chief Information Security Officer is to put strong limits and checks around these technologies—making sure each new tool helps rather than hurts the company’s safety.
How Carrie Mills and Southwest Airlines Build a Safer Airline
Mills has laid out a multi-layered plan that puts people, technology, and company culture at the heart of Southwest Airlines’ defense against cyber risks. Here’s how her team stays ahead:
- Involve Every Employee
Mills believes the most important defense against hackers is a well-trained and alert workforce. At Southwest Airlines, it’s not just the IT team watching for threats—everyone, from ticket agents to flight crews, is part of the solution. Through regular cybersecurity awareness campaigns, Southwest Airlines keeps employees informed and motivated. Mills also knows people can get tired of constant alerts; that’s why her team works to keep the messages fresh and relevant, so everyone stays aware without getting overwhelmed.
-
Work Together With Others
Being ready for cyber risks is not something airlines can do alone. Mills and Southwest Airlines are active members of industry groups like Airlines for America (A4A) and the Aviation Information Sharing and Analysis Center (A-ISAC). These groups help airlines share news of threats, talk about security incidents, and hunt for warning signs together. When one airline spots an attack, others can act before it hurts them. Mills sums it up by saying, “Information sharing is also paramount.”
Collaboration takes place at every level. Southwest Airlines not only receives news from other airlines but also shares its own lessons. This teamwork helps the entire industry become stronger, and it means that good practices spread quickly through all major players.
-
Empower Employees With Advanced Tools
Southwest Airlines uses new technologies like AI not to replace staff, but to make their jobs easier and faster. As Mills explains, AI can scan huge amounts of data, flag problems, and offer solutions—helping analysts respond to threats in minutes instead of hours.
“One way you can use AI is for responding to these threats quicker… when you have an incident you can leverage AI… so analysts can respond…as quickly as possible,” Mills says.
At the same time, Mills is careful to keep skilled people in control. Technology can offer clues, but the final decision always rests with trained security experts.
-
Stay Ready With Special Teams and Plans
Southwest Airlines has formed special teams focused on the systems inside airplanes. These professionals understand what keeps flights safe and know the technology inside and out. Their job is to spot and stop problems before they affect travelers.
Alongside these teams, the airline runs regular drills and training exercises. These tests cover everything from small computer problems to bigger cyberattacks—making sure everyone knows what to do if the worst should happen.
Three Main Recommendations From Mills and Her Team
Carrie Mills’ approach boils down to three simple but powerful recommendations for anyone facing cyber risks today:
- Build Awareness: Never stop teaching employees about new threats and safe behavior. Training should fit each person’s role—what a pilot needs to know may differ from what the IT team needs.
-
Work With Peers: Get involved with industry groups, share information when you can, and be open to learning from others’ experiences.
-
Use the Best Tools—but Keep People in Charge: Bring in advanced technology, like AI and automation, but always make sure skilled staff are watching, checking, and making the final calls.
This approach blends the best of human instinct and computer speed—a key mix when every second counts.
A Changing Landscape: Why the Stakes Are Higher Than Ever
Cyberattacks on airlines are increasing each year. The Allianz Risk Barometer 2025 now ranks cyber incidents as the top risk facing the aviation sector. These threats go beyond simple data theft. Ransomware can shut down airline websites, causing chaos for travelers. GPS spoofing—a trick where hackers send false location signals—could threaten the safety of flights themselves.
As airlines handle more data, work with more partners, and connect their planes across the world, the risks keep growing. The scale of modern attacks means that defending airlines like Southwest Airlines is more than an IT job—it’s essential for keeping the world’s people and goods moving safely.
What Sets Southwest Airlines Apart?
