what does your doctor recommend for medicine. you do not specify your condition. i am on coumiden, and if went on a dangerously long trip, i would take levonox. i wear rubber hose. i enform the FA's of my condition, and get up and walk about hourly. i stand in the exit door in the back of the plane for at least 5-10 min during that walk. request an aisle seat with your bad whatever(leg?) hanging out to the aisle. check your INR a couple times just before you leave, and lay off the healthy greens while in canada.

why do you "need to fly" if it is life threatening(clots can be). most of my friends, and I were married without daddy present. i have served as a suragot father on over half a dozen occasions.
