What to know as US prepares to require REAL ID for many air travelers next month
Most adults catching a flight in the U.S. starting May 7 will be required to present a passport or an upgraded state-issued identification card that meets federal REAL ID standards.

Officials in at least one state have requested another extension before enforcement begins.
