I fly about four - five times per year for business. The combination of cramped space and altitude/pressure has made my RSD leg swell up big-time. When it is time to deplane, it is really sentitive.

Of course, everyone is different, but for me I try to exercise as much as possible while aloft, even if it is just a little movement. Anything is better and sitting totally confined for several hours.

If you normally take some kind of diuretic for swelling, make sure to time it for maximum effectiveness during flight.
