Your domestic air travel could be delayed if you don’t have an accepted form of identification at TSA checkpoints come Wednesday, the deadline for “REAL ID.” After years of pushing it back, the Department of Homeland Security is set to enforce the May 7 deadline.

There has been a rush to secure Real IDs before the May 7 deadline at numerous locations around the country. NBC News correspondent Maggie Vespa visited one in Chicago on TODAY where the line stretched for four hours. One man told her he tried to pay someone to cut the line.

(NEXSTAR) — The REAL ID enforcement deadline officially begins on Wednesday, May 7, meaning those without a compliant ID may have a more complicated time boarding flights, entering nuclear power plants and certain other federal buildings.
