This Secure Flight program only collects basic personal information like the passenger’s name, date of birth, etc. in order to conduct “effective matching.” Additionally, this program is used to prevent people on the No Fly List and the Centers for Disease Control’s Do Not Board List from traveling via airplane. So if you see these four letters appear on your boarding pass, don’t panic! Just know that it’s part of standard protocol to ensure you and other airline passengers continue to enjoy safe, stress-free flights
Speaking of smoother travel experiences, knowing what not to wear at airports can make a big difference at security.
