JetBlue will not carry persons who require medical oxygen onboard. Due to safety reasons, we do not permit any type of oxygen to be brought on the aircraft nor do we supply medical oxygen onboard. However, in the event of an emergency, each aircraft has four oxygen masks per row for customer use.
Specific models of oxygen concentrators are approved for onboard use as long as the JetBlue requirements for oxygen concentrators are met. An oxygen concentrator is a machine that takes normal room air and, using a series of sieves, filters, and a compressor, removes nitrogen from the air, increasing the oxygen content of the resulting air to up to 96%. An oxygen concentrator is not to be confused with compressed oxygen which is prohibited on any JetBlue aircraft.
