Verify the arrangements —
After deciding on an appropriate airline, be sure to make reservations as far in advance as you can. If there are any questions or concerns about the information you received while originally talking with the airline, call again to verify the information. In addition, make it a point to confirm your in-flight oxygen arrangements a few days before your flight, and be sure to arrive early.
Take appropriate precautions when aboard — Before your plane leaves the gate, you should also take certain additional precautions. You should make sure that:
●The oxygen equipment is working properly
●You have plenty of batteries for your portable oxygen concentrator; you need enough to last the whole flight comfortably
●For oxygen canisters in a “super box,” check that the cylinders are full
●The flow meter has been set to the proper liter flow per minute
●You have access to all of your medicines, including inhalers
If you have any questions or problems, notify a flight attendant immediately.
