UAL notified me that Secure Flight is about to be rolled out by the TSA. EFF has had a lot to say about this program, which is worth reviewing (donate to EFF, help them defend your rights!).
Practical issues to watch out for:
– You need to present your full name exactly as it appears on your ID. – You will need to give your birthdate and gender while making a reservation – Do you have a redress number?
There is now a mechanism to apply for redress when you have been penalized by bureaucratic mixup and have been flagged for special scrutiny or denied the right to fly without due processes or judicial oversight.
