It most certainly can make it harder to breathe airplanes of pressurized to 8000 to10000 ft You could use your concentrator on a plane, but you have to have the right FAA approved .when you buy your ticket you have to fill out paperwork very simple . they will not let you bring oxygen tanks on a plane, they don’t supply Oxygen. It made a difference for me when I started using my concentrator on the plane the best to ask. your doctors. Hope you

Hi KellieOkeefe , I flew from New Zealand to Australia and despite my severe COOD , experienced a trouble free 3 hour flight.
I do not rely on oxygen yet.
Walking long airport corridors can be challenging so I always give myself plenty of time.
Once when feeling ill I requested wheelchair support and it was provided without hesitation .

Thank you💜💜

Flying is hard. But with an oxygen concentrator it is bearable. I try to just settle in the seat and be as calm as possible. Not to move until the plane is descending again. But it is doable

Thank you!!💜💜
