As of my last knowledge update in January 2022, Ryanair does not have a 24-hour free cancellation policy. Ryanair generally has a strict cancellation policy, and additional fees may apply for cancellations or changes to bookings. It's important to carefully review the terms and conditions associated with your specific fare type and booking to understand any potential charges or restrictions. https://airlinesupdates.com/blog/ryanair-cancellation-policy/
