Flying without a Real ID? Here's what to know at the airport

It's a nightmare for any traveler: getting to the airport and not having their ID. For many Americans, a version of that headache will become a reality starting Wednesday when the federal government begins enforcing requirements for Real ID, a national set of standards for state-issued identification documents such as driver's licenses. 

The Transportation Security Administration said that starting Wednesday, it will no longer accept IDs that don't comply with Real ID requirements.
