This is a common misunderstanding. Passports aren't required for CASS, haven't been for about 2 years. Many airlines that had CASS prior to the changeover didn't want to change their systems (time and $), but it's not required anymore, and all CASS systems coming on-line now (what airline doesn't have CASS these days?) are required to meet the new, 'without a passport' requirements (all current CASS airlines meet them too, they just have an additional field, passport #, that carried over from the 'old days' of 2005). The passport was just so that gate agents could verify a photo ID that matches your face, your ID, and is easy to check for security. That was back when an agents computer terminal didn't have to display a photo. Now, all CASS verification has to be done @ a terminal that displays a full color photo - no more 'green screens'. That's why some smaller stations still can't verify pilots in CASS - they don't have color screens for the agents to use.

If you've got the valid ID, I don't see why you need to be in uniform or carrying a second ID for CrewPass - just like you don't need to be in uniform or carrying a second ID for CASS. I wonder if TSA asks for a 2nd ID simply b/c they're trained to ask for a government ID for all regular passengers - it keeps the policy uniform.
