@cognac, Hello. It is important that when you fly with your oxygen, (it cannot be the tanks) have all paperworl with you including a doctor's note stating that you need to fly with oxygen including how many liters. Always request a wheelchair whether you feel lile you need it or not. It will get you straight through the screening without any hassels. Once through the screening, you can ditch the wheelchair.

Thanks, Terri, for your support. But other than the letter from my doctor, what is the "all paperwork" to which you refer?

@cognac , you will have to go on the airline's site and read what their requirements are. They all differ. One airline I flew on wanted info on my POC (personal oxygen concentrator). I will say that no airline ever asked to SEE any of the paperwork or check to see if I had enough battery power with me. But, you risk that one time they will ask. Now, to get back to the importance of using a wheelchair..... I got detained and missed a flight because I did not use a wheelchair. They got suspicious of the POC and me looking like I didn't actually need it. This wheelchair tip was handed down to me from another POC traveler, and boy, was she right.

@windwalker, thanks for taking the time to give me the info,especially about the tip on the wheelchair. It makes me feel much less anxious.
