There are a number of things to consider before flying with any form of oxygen concentrator. Read our statement regarding air travel with the Oxlife Independence® and FAA regulations.
Before your flight, determine your entire excursion time (which will include how many hours you are going to be in the air or just away from a power outlet) and how many batteries you will need to bring with you. Some planes have power outlets on board, so check with your airline early to find out if this is a feasible option for your flight beforehand.
If there will be no consistent access to an outlet during your flight, you will need to keep spare batteries with you for use over the course of your journey. Your battery needs will vary depending on whether or not you use pulse (oxygen delivery for every inhale) or continuous (constant oxygen delivery) air flow, so be sure to calculate the amount you will need early. If you expect that there may be any delays in flight or travel at any time, be sure to bring extra batteries just to be safe.
Similarly, most if not all airlines require prior notification (usually 48 hours) for passengers traveling with POCs, so be sure to check with your airline of choice before embarking on your flight. Most airlines do not count medical equipment against the carry-on limits during travel, but require a medical verification statement to be submitted prior to flight. Check with your airline provider for more details.
