The skydiving simulator, known as RipCord by iFLY, is a signature feature of Royal Caribbean’s Quantum Class and Ultra-Quantum Class ships. In 2026, this includes the Quantum, Anthem, Ovation, Spectrum, and Odyssey of the Seas. The experience uses a vertical wind tunnel to create a flight chamber where guests can hover in mid-air. A supportive peer "pro tip": while a basic one-minute flight is often included in your cruise fare, reservations fill up almost immediately once the boarding window opens on the Royal Caribbean app. In 2026, some of the newer ships may charge a small fee for "extended" flight times or premium sessions during peak sea days. If you're a thrill-seeker, try to book your session for a port day when the ship is docked; the lines are significantly shorter, and the view from the glass-walled chamber overlooking the destination is absolutely breathtaking.
