Verified Identity Pass, a company that promised to speed passengers through airport security checkpoints for an annual fee, has shut down, leaving some frequent fliers looking for options to avoid long screening lines.

Verified Identity Pass said it wasn't able to negotiate a deal with its creditors, which it needed to continue operating. Its service, Clear, stopped operations abruptly Monday night.

Clear originated with a program set up by the Transportation Security Administration called Registered Traveler. It was instituted when security lines swelled after 9-11.
