While a number of privately-run registered traveler programs have failed over the years, a few are starting to return which has some questioning the financial viability of such programs, according to a BNET article.

Among the newly created and resurrected programs are one at Indianapolis International Airport from iQueue and the return of a previously failed program from Clear following the purchase of its assets by Alclear.

Some of the initial issues revolve around questions from such experts as the former TSA head Kip Hawley who believes that such programs only ascertain identity but not if the person could be dangerous.

Additionally, the program at Indianapolis, iQueue, is not using biometrics to check people as the TSA no longer processes the data for them. And the new Clear program, though saying it will use biometrics, does not yet have anyone for their biometric data processing.

With pricing for joining such programs set between $169 to $197, this leaves some wondering if the new programs are little more than an additional premium traveler program and if the programs will be able to maintain the security levels manual checks by TSA agents provide.
