Yes—Delta Air Lines allows you to bring your CPAP machine onboard as a medical device, and it generally does not count toward your standard carry-on or personal-item limit. You’ll still need to pack it properly, ensure you have any required batteries (especially if you plan to use it during flight), and be prepared for security screening of the device. If you want to confirm for your specific flight or CPAP model, call 877-297-0699.
