Airports in Chicago are among those affected by a power outage at the Hartsfield-Jackson Atlanta International Airport.

Dozens of Atlanta flights to and from O'Hare International Airport and Midway International Airport were listed as cancelled heading into the evening.

Chicago and Atlanta are two of the busiest airports in the U.S.

Information posted on the website of the Chicago aviation department said 25 flights had been cancelled at O'Hare and 13 at Midway. It didn't say if all those flights were cancelled because of what's happening in Atlanta.

The aviation department also said average delays at both O'Hare and Midway were about 15 minutes — though it didn't say if there was a direct link to the problems in Atlanta and the delays in Chicago.
