If you're flying in the next few days or weeks, be prepared for potential long lines at the airport as TSA starts taking a closer look at IDs. Driving the news: Wednesday is the first day a Real ID compliant license — or another acceptable document — is needed to board a commercial aircraft in the U.

State government offices that issue driver's licenses and state IDs have seen a significant increase in demand for REAL ID and some have extended their office hours to meet the demand. Some officials have recommended people wait for a while to get REAL ID compliant licenses and cards if they don't have flight planned in the next few months.
