Are you serious?!? Why on earth would FFN be on the no-fly list?
A) TSA shouldn't have access to that info
B) You are not required to use a FFN to fly
C) Which FFN would they use? Surely you have more than one?
D) The point of the no-fly list is that you aren't allowed to fly frequently.
Idiocy like this is exactly why TSA runs roughshod over people at checkpoints. It's even not Constitutional for the TSA to force you to show ID to travel - that was settled in Gilmore vs. Gonzalez. Why on earth would you think TSA had any power or authority to scrutinize or verify your frequent flyer number?

Any violations of frequent flyer accounts are strictly between you and the airline, and punishments are limited to seizure of your miles and account, and in extreme cases, being banned from flying the airline. Perhaps you would be open to a civil fraud lawsuit.
