During the storm, Delta had a $299 fare cap each way in coach class for flights to Atlanta from coastal cities in Georgia, South Carolina, North Carolina and Virginia. It had higher fare caps for flights from inland cities.

The airline also waived change fees for passengers who altered their travel plans in affected cities.
