IMPORTANT: Upgrades made using the in-app purchase button are always charged full-price; in-app upgrades also generate a pro-rated ForeFlight store credit for the value of any unused time on the current plan. That ForeFlight store credit will apply towards the next renewal or upgrade made at the ForeFlight website. To apply that credit to extend the subscription expiration date, please contact email@example.com.
