I read in some post that although people in the airport may give u stares you have to remember the likelihood of you ever seeing them is slim to none. Probably a better chance of getting bitten by a shark in the ocean! I'd fly home 2-3 days post opp. I actually was out and about in Brussels on day two. Although you are wearing a bandana people overseas are much more accepting of how people dress compared to americans(I'm an American as well). Nobody looked at me with a questioning eye. My wife and I explored the city on day 2/3 with no issues. Day 1 you are still a bit bloody if you will. Only issue I had on day three was a little swelling in the forehead but with the bandana on nobody can tell. Oh-we upgraded to nicer seats on the plane ride as well. Was like 150 bucks. Worth it...if its an option just do it. You spent the money on the HT. Treat yourself to a nicer ride home. Where are you flying to for the procedure?
