Unless you have a seizure in front of some there is no way to distinguish if you have Epilepsy or any disorder for that matter...

Go travelling man, it will be the best thing for you! I used to let my epilepsy hold me back, but now I dabble in everything I can man, and it feels great! I've travelled all over the world and just make sure I have an adequate supply of my pills as well as any letters corresponding countries might require.
Parents will worry for the rest of your life, just keep in contact and if you have someone your seeing over there even better, make sure they know your parents and where they stand. Communication is huuuuge!
Rest and relax lots, and keep your partying (or triggers) under control.
I also like catherines comment about letting the flight attendant know, good call! I would save this information for once you board, cuz like travis said airlines can be a bitch when it comes to medical conditions, so much so it might turn you off from the whole journey.
go man goooooo

If your seizures are not controllable I can see what they are taking about but if it's just controlled by your medicine then I think they should reconsider it as a bucket list type of thing. Life is not promised tomorrow. Not that I'm trying to scare you butiI realized the more I live my life out the best I can the more I live happy and healthy. When I let people make choices for me and I follow along I die faster on the inside and I drag through life just hoping this day will end and then the next. Tell them is on your bucket list. I don't know how old you are but if you can do it by yourself that would be even greater. What if you did itwith epilepsy awareness group. That will be fun not only will you be doing what you wanted to do and being surrounded by people in case something happens but you'll be with people just like you!

I have traveled to New York and Puerto Rico but I always travel with someone . I make sure I took my meds on the plane if its a very early flight or a very late flight around the time med are due i listen to music or i sleep on the plane fine a way to relax your mind and body and make sure u tell someone on the flight that you have seizures so the look over u

Whenever I travel by plane I always like to let the head steward and the captain know that I have Epilepsy. So I made this card that I print out and give to each of the stewards/stewardesses, and captain as I am boarding the flight. I also wright my seat assignment on the card after I get to the airport and receive my ticket, so they know whom to monitor in case of an emergency. I also have attached to my watch band a MyID medical information QRC code that any responder can scan and retrieve my medical information worldwide.
