DALLAS -- Travel delays are expected Friday after reports of smoke forced a brief evacuation at Dallas Love Field Airport.

Smoke was reported inside the airport terminal, fire officials said, and passengers were forced to evacuate at about 4:30 a.m.

The smoke came from an over-heated component in an AC unit, officials said. It took Dallas Fire-Rescue crews about 20 minutes to resolve the issue.

At about 5:45 a.m., fire officials gave Love Field the "all clear" to resume operations.

The airport said on Twitter that travelers should give themselves extra time for security lines.
