Real ID Requirements Enforced at U.S. Airports

New federal Real ID requirements for air travel within the United States took effect Wednesday, requiring most passengers to present a Real ID-compliant driver's license or another accepted form of identification at airport security checkpoints. The mandate, stemming from post-9/11 security reforms and delayed for nearly two decades, led to last-minute crowds at DMVs and some confusion at airports nationwide. Despite extensive messaging, a significant portion of travelers in states like Nevada remain without Real IDs, prompting extended DMV hours and walk-in options in some areas. Passengers without a Real ID can still board domestic flights after undergoing additional security screening, as clarified by the Department of Homeland Security. Airports reported generally smooth operations and manageable wait times on the first day of enforcement, although officials advised travelers to double-check their identification and arrive early to avoid disruptions. Children under 18 are exempt from the Real ID requirement.
