1) From a web browser on your phone or computer, go to the URL that corresponds with the park you'll be visiting. Use the following list as a guide. I haven't been able to figure out the URL's for Darien Lake, Frontier City, or Great Escape.

2) Click through the popup window, making notes as you progress. This window summarizes how to get started with using the Flash Pass on your phone.
3) Once the popup window closes, you should be looking at a list of attractions at your park.
4) Create a new account for yourself via the "LOG IN" button at the top right of the web page.
5) If the site doesn't recognize that you have a Flash Pass, you may need to "Claim entitlements" by clicking on the untitled menu at the top left of the web page.
6) Alternately, if you click on an attraction, you should be able to purchase a Flash Pass or upgrade one that you already have.
7) At this point, if you're in the park, you should be able to see all of the attractions that accept the Flash Pass and you'll be able to reserve a ride time for one of these attractions.
