My Mom has MDS. Currently only affecting her red blood cells. She receives 1 unit of blood every two weeks. The day before her transfsion, her RBC is usually around 84-85. She would like to take one last vacation to the Carribbean for one week. I would travel with her. Question: would it be safe(r) for her to fly if she has a transfusion the day before she boards the plane and returns a week later?

Summarized question: Is air travel safe in a person treating for myelodysplastic syndromes?
