<p>No matter where you sit be sure you move around a few times during the flight. You do not want to develop blood clots in your legs due to stasis. It may be exercising your legs while seated or taking a cruise around the plane every so often. When we sleep in a bed we change positions every so often and our legs are not lower than our heart like they are while sitting.</p>
<p>addenda- just noticed toledo’s post #37. worth repeating, however.</p>
