Portable oxygen concentrators. Generally, the Federal Aviation Administration (FAA) prohibits the use of personal oxygen units during flights because they contain compressed gas or liquid oxygen that is defined as hazardous material.

POCs approved by the FAA may be carried and used on board United flights worldwide at no charge, in accordance with FAA regulations.
