I would not recommend being away from your surgeon only two days after surgery unless you've arranged to see another plastic surgeon regularly at home. Depending on the extent of your surgery I would recommend waiting a little longer after flying regardless. You will still be moving very slowly, likely have drains, some pain is common, and you may be nauseous from the motion. The most accurate opinion will come from your surgeon who is most familiar with your surgical plan. If you do fly, be sure not only to move around as you are able, but also consider compression hose.
There is an increased risk in blood clots if you fly within 30 days after a major surgery. Also, your surgeon will probably need to see you within a few days. I would suggest postponing your return for at least two weeks and when your surgeon says you are ready to fly. It probably would be best for you to find a surgeon in your area so you can have appropriate follow up care. Otherwise, should you have any complications, you may have to search to find a physician to see you.
