Alright, I got my ticket last week when it was released at the Nintendo World Store here in NYC. Until January you can get an Eon ticket as they have a special setup where you get it just by being inside the store.
Basically what you have to do is have your Streetpass for your 3DS console on and also make sure you have obtained the Buzznav Application in your game. When you first obtain it, it will ask you if you want to turn Streetpass on for the game, and make sure you accept it. Also, it's important you have updated your copy of ORAS to the most recent update. It won't work if none of these are on.
Now, if you happen to walk by someone with the eon ticket or go to a place that distributes the ticket (The only known place in the US that I know of to distribute it is the Nintendo World Store) and your 3DS is on then you should be set.
Once you turn on ORAS, check your Buzznav and there should be a little mailbox icon in the corner if all went well. It will say you received information from someone and if they had the Eon Ticket, it'll notify you and you'll be able to pick it up at the Pokemon Center.
The chances of walking by someone with it are slim, especially if you don't live in a big city, so it might be hard to obtain it via Streetpass.
Sorry for the long wall of text xD
