It looks as though Six Flags is offering a new “regional pass” add-on at a few parks called the FUN Jumper, in addition to the All Park Passport. From the Six Flags website it appears to be only offered in three regions at this time. Silver Passes are not eligible.
Northeast:
- Six Flags Darien Lake
- Six Flags New England
- The Great Escape
- La Ronde
Oklahoma/Texas area:
- Frontier City
- Hurricane Harbor OKC
- Six Flags Over Texas
South Texas area:
- Hurricane Harbor Splashtown
- Six Flags Fiesta Texas
