Most big airlines want to accommodate everyone to the best of their abilities, from those in wheelchairs, to the blind, to oxygen therapy patients. Since all of our portable oxygen concentrators are already approved by the Federal Aviation Administration, they are approved to be taken on board a commercial flight going to, or coming from the United States. These approved portable oxygen concentrators have been found to efficiently deliver oxygen to its prescribed user, and have been found to be safe to bring on board a plane.
One major airline that welcomes those with FAA approved portable oxygen concentrators, is Delta Airlines. However, even though a portable oxygen concentrator is approved by the FAA, doesn't mean every airline has to allow it on board their flights. Their regulations and requirements for bringing them along will also vary from airline to airline. Up until October 1st 2009, Delta had offered in flight compressed oxygen to oxygen therapy patients.
