Las Vegas Harry Reid Airport has been named among America’s least secure airport websites, while a new cybersecurity study reveals which major hubs are best and worst protected online, raising fresh concerns for travellers.
Las Vegas Harry Reid Airport has been named among America’s least secure airport websites, and a new cybersecurity study reveals which major hubs are best and worst protected online. Consequently, the findings have sparked fresh debate about digital safety for millions of travellers. Every day, passengers rely on airport websites for flight information, parking, bookings and transport updates. However, weak website protection can expose users to unnecessary cyber risks. Therefore, the report highlights why stronger online defences matter just as much as physical airport security in today’s increasingly connected travel industry.
A new cybersecurity assessment has placed Las Vegas’ Harry Reid International Airport among the lowest-ranked large hub airports in the United States for website security, highlighting the growing importance of protecting travellers from online threats before they even reach the terminal.
With millions of passengers relying on airport websites to check flight schedules, parking availability, transport options and travel updates, the security of these digital platforms has become just as critical as physical airport infrastructure. A new study by anti-detect browser company Gologin suggests that while many of America’s busiest airports have significantly strengthened their online defences, several major gateways continue to lag behind.

The study analysed the websites of America’s 30 large hub airports, measuring their performance across two essential cybersecurity indicators: HTTP security headers and Secure Sockets Layer (SSL) protection.
Each airport website received a letter grade for both categories, ranging from A+ to F. These grades were converted into numerical scores out of 100 before being averaged to produce the final rankings.
Harry Reid International Airport recorded a total website security score of 72.5 out of 100, placing it in a five-way tie for the fourth-lowest position nationwide.
The airport earned a D grade for HTTP security headers, despite receiving an A grade for SSL security. While its encrypted connections were considered strong, weaknesses in website header security significantly reduced its overall score.

The research indicates that stronger header protection could substantially improve the website’s resistance against several common cyber threats.
Harry Reid International Airport was not alone among the lower-ranked airports.
Four other major US hubs also scored 72.5 out of 100, placing them alongside the Las Vegas airport. They were:
Although these airports achieved respectable SSL security ratings, weaker HTTP security headers prevented them from ranking higher.
At the opposite end of the rankings, eight large hub airports shared first place with an impressive score of 97.5 out of 100.
Among the highest performers were:
Seven of these airports received A grades for HTTP security headers alongside A+ ratings for SSL security.
Atlanta’s Hartsfield–Jackson International Airport stood out slightly differently, earning an A+ for header security and an A for SSL, which still produced the same overall score.
These results suggest that several of America’s busiest aviation hubs have implemented robust website security measures capable of protecting users against a wide range of online attacks.
Fort Lauderdale–Hollywood International Airport secured second place with a score of 92.5, receiving an A for header security and an A- for SSL.
Meanwhile, Orlando International Airport, Dallas Fort Worth International Airport and Charlotte Douglas International Airport shared third place after each recording 90 out of 100. All three achieved B grades in header security while earning A+ ratings for SSL protection.
The rankings demonstrate that relatively small improvements in website security configuration can produce noticeable differences in overall resilience.
Honolulu’s Daniel K. Inouye International Airport recorded the weakest website security score among America’s large hub airports.
The airport received just 50 out of 100, largely because of an F grade for HTTP security headers, despite achieving a B grade for SSL security.
Four additional airports also ranked near the bottom with scores of 57.5 out of 100:
Like Honolulu, each received an F for header security while maintaining an A grade for SSL protection.
The findings suggest that header security remains a common weakness across several major airport websites.
HTTP security headers are an important component of modern website protection.
They instruct web browsers on how content should be handled securely, helping defend websites against threats including clickjacking, cross-site scripting and malicious redirects.
While SSL encryption protects information travelling between a user’s browser and the website, security headers provide additional safeguards that reduce opportunities for attackers to exploit browser behaviour.
Cybersecurity specialists increasingly regard both technologies as essential layers within a comprehensive website defence strategy.
Commenting on the study, Eugene Stepnov, Head of Marketing at Gologin, said it was concerning that several of America’s busiest airports still displayed security weaknesses that comparable airports had already addressed.
He noted that airports receiving poor header security grades could be more vulnerable to cyberattacks that inject malicious code into website structures. Such attacks may redirect visitors to fraudulent websites or silently transmit information without users’ knowledge.
According to Stepnov, many of the lower-ranked airports could significantly strengthen their protection through relatively straightforward improvements, including updating and properly configuring their HTTP security headers.
He also advised travellers to minimise risk by using fully updated web browsers when visiting airport websites and exercising caution before allowing unfamiliar website scripts to run.
As airports continue expanding their digital services, website security is becoming an increasingly important part of the overall passenger experience.
Travellers now depend on airport websites for real-time flight updates, parking reservations, transport planning, accessibility information and customer services long before arriving at the airport.
The latest cybersecurity assessment serves as an important reminder that airport security extends well beyond terminals, baggage screening and aircraft operations. Increasingly, travellers interact with airports through digital platforms before they ever arrive, making secure websites a critical part of the passenger journey. From checking flight schedules to booking parking spaces and accessing travel guidance, airport websites have become indispensable tools.
Although Harry Reid Airport performed well in SSL security, its lower score for HTTP security headers demonstrates that strong encryption alone is not enough. Cybersecurity requires multiple layers of protection, and even relatively simple improvements can significantly reduce exposure to online threats such as malicious redirects, clickjacking and code injection.
The study also highlights that many leading American airports have already implemented stronger security measures, proving that higher standards are both achievable and practical. Their performance provides a benchmark for other airports seeking to strengthen digital resilience and maintain public confidence.
For passengers, the findings reinforce the importance of practising good online habits, including keeping web browsers updated and remaining cautious when interacting with unfamiliar online content. Meanwhile, airports must continue investing in cybersecurity alongside physical infrastructure as digital services become increasingly central to modern travel.
Ultimately, protecting travellers begins long before they board an aircraft. A secure airport website helps safeguard personal information, supports trust in airport operations and strengthens the overall travel experience. As cyber threats continue to evolve, proactive investment in website security will remain essential for airports that wish to protect both their reputation and the millions of passengers who depend on their digital services every year.
Eugene Stepnov, Head of Marketing at Gologin, commented on the findings:
“It’s concerning that some of the largest airports in the country have security vulnerabilities that similar airports have already addressed. Five large hub airports recorded F grades for header security, and this means these websites are more vulnerable to cyberattacks that insert malicious code into website structures. This then allows seemingly benign elements of a website to redirect users to other websites or to send information to hackers without the user’s knowledge.
“Many of the airports with lower scores, such as Harry Reid International, could help prevent attacks like clickjacking and malicious redirects by making simple improvements to boost their security, such as updating security headers.
“Travelers can also protect themselves by using the most up-to-date web browsers while accessing web pages, and preventing scripts from running if they are not sure what those scripts do. This will mitigate the risks posed by websites that are more vulnerable to these kinds of attacks.”
Although the study assessed website configuration rather than operational airport systems, its findings underline the importance of maintaining strong cybersecurity standards across every digital touchpoint. As global passenger numbers continue to grow and airports become more digitally connected, robust online security will remain essential for protecting both travellers and the integrity of airport services.
