I have done 10 000 miles in the last 5 weeks with bad lungs. I fly 1st class, with a POC, I take my own power wheelchair with me and have wipes and wear a mask I'm traveling back and forth from Portland Oregon to the Mayo Clinic in Jacksonville Florida. 3 weeks for lung transplant evaluation and am currently in the hospital here having just completed iliac artery surgery today. All went well and now on to selection on Thursday I hope.
With care you can travel, my transplant team fully supports my traveling because they know it will fix my lung problems.
