The Department of Homeland Security estimated that only 61.2% of driver's licenses and IDs will be compliant by the May 7 deadline. A TSA spokesperson told ABC News that 81% of travelers going through TSA checkpoints currently have REAL IDs or other compliant identification.

If you're planning to hop on a plane after May for a get-away, add a REAL ID to your list of things to check before leaving or you won't be getting on a plane. May 7 is the deadline to have federally compliant identification known as a REAL ID, which the Transportation Security Administration plans to fully enforce.
