Power outages at parts of McCarran International Airport in Las Vegas are causing delays.

Airport officials said Wednesday morning on the Twitter account that ticketing and gate operations were limited in some areas of the airport and warned travelers to expect delays.

The outages impacted several, but not all terminals in the airport. Terminal 1, which was affected, serves most airlines operating out of Las Vegas. Later, the airport announced that power had been restored to the terminal but warned of more delays.

The outage started around 7:30 a.m. on Wednesday. Officials say a cable serving the airport went down and that repairs are underway.

The Reno-Tahoe International Airport tells us the outage is not affecting Reno flights, but you are always encouraged to call your carrier for updates.
