Delta Air Lines is canceling about 44 flights scheduled for Tuesday and Wednesday due to Hurricane Michael.

Atlanta-based Delta said most of the flight cancellations are Wednesday at airports in Tallahassee, Pensacola, Panama City and Destin - Fort Walton Beach.

The airline said it “does not anticipate any impact to its operation at Hartsfield-Jackson” since the storm will be southeast of Atlanta, and “winds and rain are forecast to remain within operational limits.”

As people evacuate before the hurricane makes landfall, Delta plans to operate additional flights Tuesday night from affected Florida airports.

The airline also plans to move planes to Hartsfield-Jackson International from airports in Tallahassee, Pensacola, Panama City and Destin - Fort Walton Beach on Tuesday night before Hurricane Michael makes landfall, instead of leaving the planes at those Florida airports overnight.

Some coastal airports are closing ahead of the hurricane.

Delta said it is sending water, portable generators, satellite phones, handheld devices for boarding during a power outage, and other supplies and staff to some airports to prepare to restart flights after the storm passes.

Southwest Airlines, the second-largest carrier at Hartsfield-Jackson, said all of its flights at Panama City, Fla. are suspended Tuesday and Wednesday. It plans to suspend flights in Pensacola late Tuesday.

Various airlines are waiving certain change fees for passengers with flights booked on certain days to, from or through cities in the path of the hurricane who want to change their travel plans.

Delta has a change fee waiver in place for Albany, Augusta and Valdosta, Ga.; Dothan, Fort Walton Beach, Mobile, Panama City, Pensacola and Tallahassee.

Southwest's waiver of an additional charge includes Atlanta, as well as Cancun, Havana, Tampa, New Orleans, Charleston, Norfolk, Panama City, Pensacola and Raleigh-Durham.

United Airlines' change fee waiver includes Atlanta, Charleston, Columbia, Fort Walton Beach, Greenville-Spartanburg, Mobile, Myrtle Beach, Panama City, Pensacola and Savannah.

Frontier Airlines' change fee waiver covers Atlanta, Pensacola, Birmingham and Tampa. Other carriers also have waivers in place.
