Customers with chronic illness
| While high-altitude passenger jet aircraft are pressurized, they are not pressurized to sea level or to ground level where most passengers reside. Aircraft cabins are usually pressurized to an equivalent of six or seven thousand feet above sea level (moderate mountainous elevation) and cannot, according to Federal Regulations, exceed an equivalent of eight thousand feet.
At these cabin pressurization levels, some persons with heart or lung problems may experience breathing or other difficulties that can be prevented by the use of supplemental or medical oxygen.
Customers with chronic illnesses, especially asthma, emphysema, chronic bronchitis, COPD, pneumonia, anemia, cancer, angina, CHR (heart failure) or other chronic heart or lung conditions are encouraged to consult with their physician before flying.
If you require medical oxygen during flight, please visit our Medical Oxygen page for information about the options that are available to you.
