I’d like to make some things clear in response to the Nov. 11 editorial “Tricking the TSA.”

Anyone who is on the FBI “no-fly list” or is considered a risk to aviation security is precluded from printing his own boarding pass. Also, the Transportation Security Administration (TSA) has been working and continues to work with industry to prevent passengers from manipulating boarding pass data, which is a criminal offense. The TSA has created a layered security approach so that all passengers who go through checkpoints, including those in the TSA “PreCheck” program, are subject to multiple security measures including behavior detection, screening and canine assessment that secure travelers and our nation’s aviation system.
