The Real ID deadline is Wednesday, May 7. Travelers flying within the United States will need the compliant identification to pass through airport checkpoints, marking a significant shift in security requirements.

While the Homeland Security chief said travelers without a Real ID can still fly — for now — they’ll be subject to extra screening. So everyone should brace for even longer airport security lines and delays.
