Are there blood clots on long distance flights?
More than 300 million people travel on long-distance flights (generally more than four hours) each year. 1 Blood clots, also called deep vein thrombosis (DVT), can be a serious risk for some long-distance travelers. Most information about blood clots and long-distance travel comes from information that has been gathered about air travel.
When does a blood clot travel through the body?
Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot develops deep in a vein. These clots typically occur in a leg, a thigh, or the pelvis but may also develop in an arm. DVT can become dangerous if the blood clot breaks off and travels through the bloodstream to the lungs.
What are the symptoms of a traveling blood clot?
The most common symptoms of DVT are swelling in an arm or leg, tenderness that isn’t from an injury, and skin that feels warm and is red in the area of the clot. A clot usually forms in just one leg or arm, not both.
How long does it take DVT to get to lungs after breaking?
The time between when a blood clot breaks to when it reaches the lungs is a few SECONDS. Dr. Gashti specializes in the diagnosis and treatment of vascular disease including abdominal and aortic aneurysm.
How can you avoid blood clots While flying?
The best way to avoid a blood clot is to move around as much as possible during your flight. Get up out of your seat at least once an hour, and move your limbs frequently while sitting — flexing and bending your feet, ankles, and knees. If you are worried about blood clots, talk to your doctor before flying.
Why do blood clots form?
In normal situations, causes of blood clots are non-threatening, and they form in response to injury in the body, such as a cut or break in the skin. The clots form when the cells in the lining of the blood vessels form platelets that act as a plug in the wall of the vessels.
How do blood clots occur?
Blood clots occur when blood coagulates inside a blood vessel to stop bleeding during an injury. Blood clots are comprised of platelets and fibrin , which come together at the site of the injury to form a plug, or clot.
What happens to the blood in your legs when you fly?
When we fly, the blood that pools in our legs has a tendency to form clots, which can grow large enough to obstruct a vein and cause a painful and dangerous DVT (deep vein thrombosis). If the clots are able to move into the lungs, they can cause a life-threatening pulmonary embolism.
What should you do if you have a blood clot on a plane?
While flying, keep your blood moving. Try to get up and walk the plane at least once every 1-2 hours. While you are seated, do not cross your legs. Keep your legs as straight as possible to make it easier for your blood to circulate. Do leg and foot exercises as these will help to move blood and prevent clots.
Can a pulmonary embolism cause a blood clot on an airplane?
The longer blood sits still, the greater the chance of a clot. Bent knees or crossed legs make it even more difficult for blood to circulate. When one is stationary for 1-2 hours, the risk of a DVT or pulmonary embolism increases. On airplanes, many passengers are seated in the same position for at least 2-8 hours.
When is it safe to fly with a blood clot?
Your risk of developing a DVT or PE while flying may be elevated, if you have a history of blood clots or have recently been treated for the condition. In order to prevent these risks, you need to wait at least 4 weeks after the blood clot treatments before taking to fly.

Why do you get blood clots when you travel?
Blood Clots and Travel: What You Need to Know. Blood clots can form in the deep veins (veins below the surface that are not visible through the skin) of your legs during travel because you are sitting still in a confined space for long periods of time. The longer you are immobile, the greater is your risk of developing a blood clot.
What are the dangers of flying with heart disease?
One of the biggest risks for people with heart disease who are flying is developing a blood clot or venous thrombosis. Various factors can increase the risk of developing a blood clot while flying. These include dehydration, lower cabin oxygen levels, and sitting for long periods of time.
