The calamitous power outage Sunday at Hartsfield-Jackson International Airport will continue to affect flights the day after.

Delta Air Lines has already canceled 300 flights for Monday.

The Atlanta-based carrier, which has its largest hub at Hartsfield-Jackson, said most of the Monday flight cancellations are early morning flights into Atlanta. That will allow its operation to “more quickly return to normal,” according to the airline.

Delta said its flight schedule in Atlanta is “expected to return to normal by Monday afternoon.”

If you’re scheduled to fly at the start of the work week, you should check your flight status on your airline’s website or app.

Many airlines are also waiving certain change fees for passengers with flights booked for Monday to, from or through Atlanta who want to change their travel plans to avoid possible disruptions.

Delta Air Lines has posted a statement on the impact of the outage on flights Monday:

Delta customers scheduled to traverse Atlanta Monday are encouraged to check their flight status as approximately 300 flights will be cancelled due to Sunday's power outage at the Atlanta airport affecting all airlines there. The largest number of cancellations on Monday are early morning and inbound to Atlanta to give the operation there an opportunity to more quickly return to normal. Delta previously cancelled approximately 900 mainline and Delta Connection flights Sunday and diverted 48 flights to alternate airports due to the nationwide groundstop for Atlanta-bound flights. The airline is working to reaccommodate affected customers on alternate flights. Cancellations are designed, in part, to allow the operation to best reset Monday.
