Travelers with respiratory difficulties who use commercial airlines need to be aware of a new labeling requirement for ventilators, respirators, positive airway pressure devices (i.e., CPAP, BiPAP) and personal oxygen concentrators.
Trying to travel without following the new regulations can result in being denied a seat, or being required to turn off the respiratory equipment during the flight. The new rule is from the U.S. Department of Transportation (DOT), and relates to existing Federal Aviation Administration (FAA) regulations.
