As of 2025, wearing a mask at airports is no longer a mandatory requirement for passengers or employees. This relaxation of rules reflects a broader trend toward normalising travel conditions post-pandemic, with many airports and airlines worldwide lifting previous mandates. However, the question of whether to wear a mask on a plane remains significant, given the continued circulation of various respiratory viruses, including COVID-19, influenza, and Respiratory Syncytial Virus (RSV).

Mask Guidance for Air Travel in 2025

While masks are not required, many health experts suggest that wearing a mask while traveling can still provide significant protection, particularly in confined and crowded spaces like airplanes. Dr. Maria Gonzalez, an infectious disease specialist at Global Health Network, emphasises the importance of choosing an effective mask for optimal protection. She suggests wearing an N95 or KN95 mask, which are regarded as the gold standard for their high filtration capabilities and snug fit. These masks effectively filter out airborne particles that could carry viruses, providing a higher level of protection against respiratory infections.

If N95 or KN95 masks are unavailable, Dr. Gonzalez recommends using a surgical mask. Although surgical masks are less effective than N95s in filtering out smaller particles, they still offer a reasonable degree of protection against most respiratory viruses, including influenza and some strains of COVID-19. An additional layer of protection can be achieved through “double masking”—wearing a surgical mask with a cloth mask on top to keep the surgical mask securely against the face. This combination can provide protection comparable to that of a KN95 mask, making it a good alternative if more advanced masks are unavailable.

Current Virus Trends and Risks

According to the latest report from the World Health Organisation (WHO), respiratory viruses such as RSV, COVID-19, and influenza remain prevalent in many regions globally. Elevated RSV activity has been noted particularly among young children, who are more susceptible to severe symptoms. COVID-19 cases have continued to increase in certain regions, including parts of Europe, Asia, and North America, where cooler weather has led to more indoor gatherings. Meanwhile, influenza is on the rise in many parts of the world, especially in areas with high travel activity. Given this landscape, wearing a mask on a plane can still significantly reduce your risk of exposure to these viruses, even if you are the only one masking up.

Health experts, like Dr. Sarah Mitchell from the International Society for Infectious Diseases, point out that the rise in multi-virus activity is particularly concerning for travellers. “With so many viruses circulating at once, including some that have developed resistance to previous treatments, it is more important than ever to take personal precautions,” Mitchell explains. This means that, even with the removal of formal mask mandates, the decision to wear a mask remains a highly personal but recommended choice, especially for those with underlying health conditions or compromised immune systems.

The Practicalities of Masking While Traveling

Despite the lower risk of contracting an illness due to filtered air on planes while in flight, Dr. Gonzalez advises maintaining a mask while moving through crowded areas, such as airport terminals, security lines, and boarding areas, where the risk of exposure is higher. “Airports can be hotspots for viral transmission due to the large number of people in close proximity, many of whom might be coughing or sneezing,” she notes. “Even if air filtration on planes reduces the risk during the flight, the journey through the airport poses significant exposure risks.”

In addition to wearing a mask, Dr. Mitchell underscores the importance of practicing good hygiene to mitigate the risk of illness. Regular hand washing with soap and water for at least 20 seconds, using alcohol-based hand sanitisers, and covering your mouth and nose when coughing or sneezing are essential practices to protect yourself and others from respiratory infections. These measures, combined with mask-wearing, provide a comprehensive approach to minimising your risk of contracting or spreading illness.

Conclusion

In 2025, wearing a mask in airports and on flights has become a matter of personal choice rather than a requirement. However, given the persistent presence of respiratory viruses, wearing a mask can still be a prudent decision to safeguard your health while traveling. Whether you opt for an N95, KN95, or surgical mask with double masking, each provides a level of protection that can help reduce the likelihood of infection. Complementing mask usage with good hand hygiene, avoiding close contact with sick individuals, and maintaining physical distance when possible can further minimise the risks associated with travel. As travel continues to return to normal, being mindful of these practices can help ensure a safer and healthier journey for everyone, allowing travellers to focus on enjoying their destinations rather than worrying about potential health risks.
