SAN FRANCISCO (AP) — REAL ID requirements for those flying within the United States begin after more than 20 years of delays. Starting Wednesday, travelers taking a domestic flight and using a state-issued ID to get through security must have one that meets federal REAL ID requirements. Homeland Security Secretary Kristi Noem assured people Tuesday they will be able to fly after clearing additional identity checks. The Transportation Security Administration warned people who don’t have identification that complies with REAL ID requirements to show up early and be prepared for advanced screening to avoid causing delays.
