Airlines rules for medical oxygen: The airline rules for use or taking oxygen equipment during a flight vary per airline. In general one can find this information on the airline's website or ask your travel agent. An airline can arrange the supply of medical oxygen at a certain cost. One will have to provide a doctors prescription so the airline company can make sure that enough oxygen will be on boar. Please note there is often a limit in the amount of oxygen an airline allows on board, the same counts for the number of oxygen patients per flight. When it comes to taking own equipment like portable concentrators on board for use during the flight the airline company generally stipulates on it's website which models are allowed. OxygenWorldwide does not arrange oxygen on flights.
