The Metropolitan Airports Commission is reviewing complaints from Minneapolis residents about airport noise after an increase in number of overnight flights.

Noise complaints from residents have increased this summer due to additional flights to and from the West Coast at night, said Patrick Hogan, director of public affairs and marketing for the MAC.

Airlines make scheduling changes from season to season, and as those changes occur some flights can come later in the night, he said.

But Hogan also attributed some of the complaints to comfortable temperatures in recent weeks.

"We've had some really good weather this year where people have been able to leave their windows open a little more than they would have in some of the hotter summers," he said. "So people are noticing the noise more."

Also Monday, MAC officials said massive construction work will begin at the airport in 2016 and last for about three to five years.

In January 2016, the MAC will resume full control of Concourse G in Terminal 1 from Delta Air Lines, which now has exclusive control of the management of the concourse and its concessions.

In other matters, MAC officials said the airport is working to fix Wi-Fi connectivity issues after customers had trouble accessing the free public Wi-Fi.
