Cost of the U.S. No-Fly List
Someone did the analysis:
As will be analyzed below, it is estimated that the costs of the no-fly list, since 2002, range from approximately $300 million (a conservative estimate) to $966 million (an estimate on the high end). Using those figures as low and high potentials, a reasonable estimate is that the U.S. government has spent over $500 million on the project since the September 11, 2001 terrorist attacks. Using annual data, this article suggests that the list costs taxpayers somewhere between $50 million and $161 million a year, with a reasonable compromise of those figures at approximately $100 million.
