Personally i dont feel distance or travel should be much of a factor. I recently flew about 20 hours each way from new york to australia and spent 2 weeks there, for an all FUE work with Dr Woods.
I wore a gilligans island hat on the way back from australia, and did not have to take it off, but i did get thoroughly searched in syndey on the way back, including taking my shoes off.
In L.A The guy in front of me, they asked him to remove his hat. I asked the lady if I could keep my hat on, and they said no problem so long as the buzzer does not go off.
I would recommend considering traveling to a clinic, if needed, for you.
Whatever you do, will last with you for many years, the rest of your life.
So be extra careful, and consider traveling anywhere in usa, canada, europe, australia, or myself, even to the moon if needed to get the best work done for you.
