Umm, what happened to the OP? Tejolote, are you there?

I read the website you pointed to with recovery precautions, and it's consistent with what I was told to do. As Harleycat as already pointed out, several of them are inconsistent with a Europe - Seattle journey:

"* During sitting, keep in mind that your knees have to be lower than your hips...
* Do not bend forward at a sharp angle. Maintain an angle of maximally 90°.
* During sitting, keep your legs somewhat outward.
* Be careful not to twist at the hip. When you turn, be sure to move your entire body around.

To counter swelling, elevate your feet higher than the heart level while you are lying down. Do this during your rest periods for 45 minutes to 1 hour, 2-3 times a day.

Do not sit longer than 30 minutes at a time. "

I would also be concerned about trying to move around the aircraft if there's turbulence, using the aircraft toilet during the flight, getting your carry-on luggage in/out of the overhead bin, etc.
