Overview
- Six Flags announced the Flex Pay option on Monday, September 7, 2026, making the program available at online checkout for eligible purchases of $49 or more.
- Flex Pay is powered by Upgrade and requires applicants to be 18 or older to complete a brief application that gives Upgrade's lending partners the credit and identity information they use to approve loans.
- Six Flags discloses APRs from 0% to 36%, notes some plans may be interest-free, allows down payments in some cases, and permits borrowers to pay off balances early without penalty.
- The company and reporters stress that Flex Pay is an installment loan for a time-limited season pass, not a recurring membership, so interest can make a pass cost more than paying up front or choosing a zero-interest competitor plan.
- Separately, Six Flags Darien Lake confirmed it will not hold Fright Fest this year, a local operational change reported by the park and regional media that is not presented as linked to the Flex Pay rollout.
