BS!
“BS!”
No, sorry, it’s not.
Oxygen bottles and LOX are strictly verbotten on Commercial passenger aircraft in the U.S. by FAA Regulation. Portable oxygen CONCENTRATORS are not, but the use is strictly regulated, and only FAA pre-approved devices are allowed. “Aircraft Supplemental Oxygen” is available on most large aircraft, with advance notice (48-96 hours, depending on carrier) and at additional cost, that’s not cheap.
This is NOT available on may regional aircraft.
Not BS.
Concentrators only, with 1.5 times the batteries needed for flight times and layovers. So if ten hours are to pass from the beginning of Flight A to the end of Flight B, patient needs 15 hours of charged batteries. Doctor’s note and a release saying that the patient can fly at the maximum LPM are required.
