Unfortunately, this is a sad but true fact about US Airways. No medical waivers, no favors. period. I was in a situation a little over 2 years ago where I came down with a weird stomach virus and was throwing up blood. This was 48 hours before departure to MSY. I couldn't get an appointment to see my gp so I went to an emergency room. I called US and offered to give the name of hospital/time I was there/name of dr seen, etc but my pleas fell on deaf ears. Fortunately, I did get better in time but it goes to show that they really have no compassion.
