Flying First Class Won’t Prevent Blood Clots

According to new guidelines on deep vein thrombosis, sitting in first class on an airplane wont prevent blood clots. With deep vein thrombosis, a blood clot forms in the deep veins, especially in the lower legs or pelvis, restricting blood flow.

As a healthy person, you’re no more likely to develop a blood clot in a leg on long haul flights than passengers in roomier first-class. Conditions that do put people at higher risk of DVT on flights of six hours or more include:

  • a history of a previous blood clot, active cancer, recent surgery or trauma, immobility, older age, thrombophilia (an inherited blood disorder that makes people more likely to form blood clots), estrogen use (including birth control pills) and obesity.
  • Passengers who are especially tall or especially short may also have an increased risk, they state.

It has been recommend that you do not take Aspirin or other blood thinners to prevent DVT on long haul flights, unless people are at particularly high risk, and only then after they have weighed the benefits against the risks.
