Starting Friday, the Federal Aviation Administration will reduce flights by 10% at 40 major airports, including Hartsfield-Jackson Atlanta International Airport.

Travelers with plans to fly amid the government shutdown are searching for refund policies related to flight delays or cancellations.

Transportation Secretary Sean Duffy said there will be a 10% reduction in flights at 40 airports, prompted by a historic government shutdown.

The Federal Aviation Administration released the full list of airports Thursday, including major hubs such as Atlanta, Los Angeles, Chicago O’Hare, and Newark Liberty. FAA Administrator Bryan Bedford said the changes aim to “put relief where it will do the most good” while ensuring flight safety remains uncompromised.
