@bgilchr7 Best wishes to you too. If you are going to be in Colorado, consider the impact on your oxygen saturation level. It goes down with higher altitude. Last year I flew to Florida with my portable Inogen Rov6. I have multiple oximeters to watch my oxygen levels. I had tested and they said I didn't need oxygen on the plane. But my oximeters said differently. My O2 dropped when plane reached flying altitude and I had to use my Inogen to keep my O2 in safe zone. You need to check with airlines about what you can bring with you on airplane = they do allow portables and our batteries but you need to have enough for more than the time of the flight.
