2002 Introduction of portable oxygen concentrators (POC) weighing less than 10 pounds

Dr. Tom Petty had long recommended that POCs should ideally weigh less than 10 pounds. Since that goal was first achieved in 2002, POCs have continued to become more lightweight. Some models currently available weigh less than 5 pounds.

FAA-approved portable concentrators

Since 2009, passengers requiring oxygen may use FAA-approved portable concentrators on most commercial flights. Passengers with POCs must give advance notification to the airline of their intent to travel with POCs, as well as present their prescription for oxygen and their release for air travel from their physicians.
