Airline travelers who don’t have a REAL ID, a compliant driver license, by the May 7 deadline will still be allowed to fly—but only after undergoing further scrutiny. Department of Homeland Security Secretary Kristi Noem told lawmakers Tuesday about the change.

Kristi Noem, the secretary of homeland security, said that travelers without a federally recognized document would face additional screening on Wednesday but would not be barred from flights.

Travelers who don’t yet have a new federally approved identification card should expect delays at the nation’s airports but will still be able to board domestic flights, Homeland Security Secretary Kristi Noem said.
