A Mesh Sufferer needed to fly to have a removal surgery... this is what she was told by the friendly folks at Delta Airlines. It may apply to other airlines as well...
" I didn't know about it either, found out by accident. I was trying to make reservations for my next surgery with Dr. Raz. I chatted with an employee online, he told me to call delta and ask for the medical discount. There was no income qualification for this. It applies to coach only, but I did save $32 one way. Every little bit adds up. They just asked where the surgery was going to be."
