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.

Travelers flying within the US starting Wednesday must use a state-issued ID that is “REAL ID compliant” or be subject to further screening. Things seemed to be operating relatively smoothly at a sampling of US airports Wednesday morning.
