I have been told a few times that I am on the no fly list, so I avoid planes - that, and I am nearly 7 feet tall.
Is my only way to discover if I am allowed on an airplane is to buy a ticket and get subsequently denied on the boarding gate/security? No FOIA request, or anything similar, to circumnavigate this?
Yes this is insane. I’m a U.S. citizen and if I’m not allowed to fly because of some arbitrary national security measure then that measure had better be public information and known before I book a ticket.
If my government has denied you the right to travel without telling you why I genuinely and sincerely apologize and take responsibility because it should not work like that and ideally I should be able to vote out the people who made that decision.
Are you sure of that? Rights attributed generally to "the people" in the constitution can be limited from being enjoyed based on immigration.
For instance, "the people" have the right to keep and bear arms but god help you if you're here irregularly or on a tourist visa and do not meet one of the exemptions. Sure non-immigrants are persons but federal law doesn't give a fuck.
What if you are a US citizen, and it has recently been discovered you have been secretly dealing arms to Russia against current sanctions. And while authorities do not currently know your location they suspect you will be flying to/from Russia very soon?
That's totally different - indictments are usually sealed before arrests in the kind of case you're talking about and there is longstanding precedent for that to prevent flight from prosecution. They would arrest you for ITAR and IEEPA violations before you board. That kind of thing happened long before the no fly list. That is different than an opaque list with a million people on it most of which have never been accused of anything and where there is an expensive appeals process and the government is allowed to use secret evidence.
I had the impression from the article that anyone could submit the form requesting information if they were so inclined; I just meant that most people probably only find out when they're denied. Then again, being 7 feet tall they might be doing you a favor.
