All of your pass riders travel unrestricted without you. I wouldn't play with your travel benies if you call in sick and then nr yourself. If you called in and still want to go on vacation, js on another airline. If it is legit and you can still fly as a passenger just not well enough to be the pilot, call the cp support center and the will clear you to nr no problem. Personally I wouldn't just chance it wo permission on a sick call. I have heard some stories but who knows it might be just stories of people getting their privileges yanked.
