I'm pretty new so I can't remember exactly but pretty sure there were very limited airlines for zed by parents (Iceland air and a few others). I know that's the case for companions but can't remember parents. Health benefits start the first of the month the month after you start. Flight benefits are you can jumpseat quick (gets you into CASS first week) all others are 30 days and zed is 6 months. Someone can correct me if I'm wrong on the first part
