Travelers who used to avail Clear, a service that allowed registered travelers to bypass security checks at Denver and other international airports, now will have to stand in line with everyone else.

The Transportation Security Administration created the Registered Traveler program that lets companies establish exclusive security lines at airports.

Verified Identity Pass, which operates its Clear program in 18 airports including Orlando Atlanta, Denver, San Francisco and Washington Dulles International Airport, informed Monday that it would shut operations at every airport.

According to Verified's website statement, the company remained unable to negotiate an agreement with its senior creditor to continue operations. However, the company provided no information about whether enrollees would get refunds or not.

David Castelveter, a spokesman for the Air Transport Association, an airline trade group that had opposed the program, said, "I don't see any future in Registered Traveler."

Massive lines at airports after 9/11 attacks had compelled people to demand for faster screening.

But the Transportation Security Administration insisted that passengers enrolled in Registered Traveler should also go through the same security screening as ordinary travelers.

Assistant aviation director at Oakland International Airport, Deborah Ale Flint said that the adverse economic situation affected Clear's ability to operate.

It is worth mentioning here that the Obama administration has not appointed a new chief for Transportation Security Administration.

Earlier this month, more than 260,000 travelers were signed up by Clear to utilize its special lanes.
