If I am not wrong , can Redress number help you from not getting SSSS on domestic flights within the states? Do people get SSSS on only international flight to and from US? I have redress number and I rarely fly but I did fly domestic twice in last 12 months and got no SSSS but on return trip from Asia, I got SSSS both times. My wife got her first SSSS on flight from Canada on United . Some said SSSS is common on united airlines flight from Canada to USA
