Hartsfield-Jackson Atlanta International Airport experienced a power outage on Sunday, which led to the cancellation of over 1,200 flights on Sunday and Monday. 

Activity at the world’s busiest airport came to a halt after a fire in an underground electrical facility caused the outage at 1 p.m on Sunday. Power returned to the airport early Monday morning. 

Delta Air Lines suffered the most of any airline, cancelling more than 1,200 flights between Sunday and Monday. Some believe the airline won’t resume normal operations in Atlanta until Tuesday.

CNN reporter Betsy Klein documented the experience on Twitter, showing how the airport slowly descended into chaos as passengers were left in the airport with limited food, water, and information about the power outage after de boarding their planes.

Other passengers and observers commented on the power outage and found it to be equally frustrating:
