Most big airlines want to accommodate everyone to the best of their abilities, from those in wheelchairs, to the blind, to oxygen therapy patients. Since all of our portable oxygen concentrators are already approved by the Federal Aviation Administration, they are approved to be taken on board a commercial flight going to, or coming from the United States. These approved portable oxygen concentrators have been found to efficiently deliver oxygen to its prescribed user, and have been found to be safe to bring on board a plane.
One major airline that welcomes those with FAA approved portable oxygen concentrators, is Delta Airlines. However, even though a portable oxygen concentrator is approved by the FAA, doesn't mean every airline has to allow it on board their flights. Their regulations and requirements for bringing them along will also vary from airline to airline. Up until October 1st 2009, Delta had offered in flight compressed oxygen to oxygen therapy patients.
One thing they have in common, is you always need to let them know well ahead of time that you need to bring a portable oxygen concentrator with you on your flight. If you're flying with Delta, you will need to tell them this information when you purchase your ticket. One great thing is, your portable oxygen concentrator and an accessory bag used to bring along the things you need, will not count against your carry on limit.
Be sure to check the list, and visit Delta's website http://www.delta.com/content/www/en_US/agency/our-products-and-services/onboard-oxygen-and-assistive-devices.html for any more details before booking your flight. Here is a list of the FAA approved portable oxygen concentrators that Delta allows on its flights: Inogen One, AirSep Lifestyle, AirSep Freestyle, SeQual Eclipse, Respironics EverGo, Delphi RS-00400 (EVO Central Air), Invacare XPO2.
One requirement for using one of these POCs on board a Delta flight, is it can't be used if you are sitting in an exit row or bulkhead seat. There is also a special sticker needed for the AirSep Lifestyle, but this is not one of the POCs we sell at American Medical. POCs are approved to be used on board, because oxygen tanks are not allowed.
If you intend on bringing them to use when you've gotten to your destination, you can bring them with you on your flight with Delta, as long as they are empty and completely free of pressure, and the batteries are packed separately from the tanks. The tanks and battery will be counted as part of your carry on limit. If they contain liquid or compressed oxygen, you will not be allowed to bring them aboard the flight.
