Can I take my CPAP machine on Ryanair?

Certain items such as Portable Oxygen Concentrators (POC) that meet regulatory requirements are approved for onboard use. Other medical equipment such as a CPAP or Portable Dialysis machine can be carried but not used onboard.



Yes, you can take a CPAP machine on Ryanair, but there are specific rules regarding its carriage and use. According to Ryanair’s 2026 policy, you are permitted to carry your CPAP machine as cabin baggage for free; however, it must count toward your standard carry-on allowance unless you obtain a "Medical Equipment Waiver Letter." To get this waiver, you must contact Ryanair's Special Assistance team at least 48 hours before your flight with a doctor's letter confirming your need for the device. With the waiver, you can carry the CPAP in addition to your regular cabin bag at no extra cost. It is a peer-to-peer "critical rule" to know that CPAP machines are not permitted for use onboard Ryanair flights due to the aircraft's power limitations and safety protocols; you may only transport it for use at your destination. Ensure your machine is packed securely, and be prepared to show your waiver letter at both the bag drop desk and the boarding gate to avoid any unexpected baggage fees.
