Why You Should Never Wear Leggings on a Plane, According to a Flight Expert

Air travel has become more accessible and frequent than ever before, making comfort a top priority for many passengers. One of the most popular travel outfits consists of leggings paired with an oversized sweater or hoodie. However, while leggings may seem like the perfect choice for a long-haul flight, flight experts warn that they may not be the safest or most practical option for air travel. Here’s why you might want to rethink wearing leggings on your next flight.

1. Fire Hazard Risks

Safety is one of the biggest concerns when it comes to air travel. While plane crashes are extremely rare, emergencies such as fires can occur. According to flight safety experts, passengers should avoid wearing synthetic fabrics like polyester and nylon—common materials found in leggings—because they are highly flammable and can melt onto the skin in extreme heat situations. In the event of an emergency evacuation, wearing natural fibers like cotton, wool, or denim can provide better protection against burns.

2. Leggings and the Risk of Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis (DVT) is a condition where blood clots form in deep veins, usually in the legs, due to prolonged periods of immobility. Tight-fitting clothing like leggings can restrict circulation, increasing the risk of clot formation, especially during long-haul flights. Flight attendants and doctors recommend wearing loose-fitting clothes and compression socks to maintain healthy blood flow and reduce the risk of DVT.

3. Potential for Discomfort and Swelling

Airplane cabins are pressurized, but the reduced air pressure and prolonged sitting can still cause swelling in your feet and legs. Wearing tight leggings can make this discomfort worse, as they do not allow proper circulation. Loose or breathable pants, such as joggers or travel-friendly trousers, are better alternatives that accommodate swelling and promote circulation.

4. Unhygienic and Poor Breathability

Airplane seats, despite regular cleaning, harbor bacteria and germs from numerous passengers. Leggings, especially those made from synthetic materials, are not very breathable and tend to trap moisture, leading to increased sweat and bacterial growth. This can create an ideal environment for skin irritation, rashes, or even infections, particularly on long flights where movement is limited.

5. Leggings and Emergency Evacuations

In case of an emergency evacuation, passengers may have to use inflatable slides to exit the aircraft. Some flight attendants caution against wearing leggings because the smooth, synthetic fabric could make it difficult to slide down properly or may even cause burns due to friction. Heavier, non-slippery fabrics such as cotton or denim are preferable in such situations.

6. Temperature Variability and Comfort

Airplane cabins often experience fluctuating temperatures. While the boarding area may feel warm, the cabin can become quite cold during the flight. Leggings, particularly thin ones, may not provide enough insulation against the cold. Opting for layered clothing, such as breathable pants with a soft fabric layer underneath, can help regulate body temperature more effectively.

7. Dress Code Policies and Airline Restrictions

Although rare, some airlines have dress codes that prohibit overly tight or revealing clothing. In 2017, United Airlines denied boarding to two girls wearing leggings as part of their passenger dress code policy. While most travelers will not encounter such restrictions, it’s always best to dress in a way that avoids any potential issues.

What to Wear Instead?

If leggings are not the best option for air travel, what should you wear instead? Here are some comfortable and practical alternatives:

• Loose-fitting, breathable pants: Opt for soft joggers, cotton trousers, or travel-friendly pants that allow movement and airflow.
• Compression socks: These help reduce swelling and lower the risk of blood clots.
• Layered clothing: A comfortable T-shirt paired with a light jacket or sweater provides flexibility to adjust to temperature changes.
• Comfortable, supportive shoes: Slip-on shoes are ideal for security checks and walking through airports.

Final Thoughts

While leggings may be a go-to outfit for many travelers, they come with several downsides that make them less than ideal for air travel. From safety concerns and circulation risks to hygiene and emergency evacuation issues, experts recommend choosing alternative attire that prioritizes comfort and practicality. Next time you board a flight, consider swapping out your leggings for a more travel-friendly option—your body (and safety) will thank you!
