I never imagined that I could travel in such tranquilly once more. Finding out Which airlines provide in-flight oxygen or portable oxygen concentrators (POCs) in flight opens doors. I assumed they were closed for good. I received courteous and patient treatment from the airline staff. They made sure I was comfortable, checked on me, and gave me comfort. I was optimistic rather than nervous. I knew that this voyage will always hold a special place in my heart when I finally got to see my family after all this time.
