McCarran Airport will have a planned power outage at 1 a.m. Saturday.
Crews have conducted several tests over the past few days after a series of outages inside Terminal 1 on Wednesday.
The initial outage lasted about 90 minutes, causing long lines and delayed baggage for hundreds of passengers.
McCarran officials say the issues were caused by a downed cable that serves the airport.
