Wednesday, May 7 is the first day a Real ID compliant license — or another acceptable document — is needed to board a commercial aircraft in the U.S. Why it matters: If you aren't Real ID compliant, you may experience longer wait times at the airport,

Transportation Security Administration officials will not accept state-issued driver’s licenses or ID cards that are not REAL ID compliant. Under the new REAL ID enforcement rules, all airline passengers 18 and older will need REAL ID-compliant identification or another federally accepted ID at airport security checkpoints.

As of May 7, travelers flying domestically in the U.S. must present a REAL ID-compliant form of identification at airport security checkpoints or expect to go through additional security measures.

Domestic fliers will need the ID or an approved alternative to get through airport security. Otherwise, they face extra scrutiny

After nearly 20 years of delays, the Real ID deadline is finally here. Beginning May 7, Americans planning to travel domestically are required to use the enhanced form of identification. The Transportation Security Administration said it will no longer accept IDs that don't comply with Real ID requirements.
