US Airports Restrict Boarding for Passengers with Delayed Passport Updates

Airports in Dallas, Atlanta, New York, and New Jersey are enforcing stricter passport validity checks, blocking boarding for travelers who have not completed a required update procedure. This appears to be an administrative enforcement action rather than a change in federal international travel regulations, though the exact legal basis remains unclear. The move could disrupt travel for affected passengers and signals tighter document compliance at major US hubs.
