We’re not equipped to transport or provide medical oxygen or other hazardous materials and/or contained gas. Unfortunately, any Customer who requires a constant supply of compressed or liquid medical oxygen cannot travel on Southwest. We may request documentation from a licensed physician to verify that the Customer can complete the flight safely and without the use of medical oxygen.
Liquid oxygen cannot be carried onboard. If a liquid oxygen unit is empty (and contains a gauge or color indicator verifying the unit is empty), then the unit can be transported, as long as the valve remains open.
