SAN FRANCISCO (KGO) — San Francisco International Airport is letting travelers know of a partial power outage Wednesday morning.

SFO says that the outage is affecting parts of Terminals 1, 3 and International. They say crews are on scene working to restore power.

The outage is happening the same morning Alaska Airlines is moving from Terminal 2 to the new Harvey Milk Terminal 1.

Starting Wednesday morning, almost every Alaska Airlines operation is moving, including ticket counters, boarding gates and baggage claim.

The only thing not moving right now is the Alaska Airlines lounge, which is staying in Terminal 2 until the new lounge opens in Terminal 1 next month.

The relocation comes as a part of Terminal 1’s $2.5 billion renovation, which includes a brand new security check-point, additional gates and new concessions.
