After making landfall in the Florida Keys on Sunday, Hurricane Irma made a beeline up the Florida peninsula, hitting the city of Naples on the mainland and moving up north at a steady pace. Next in its crosshairs: Georgia and Alabama.The storm is just north of Tampa at midday Monday, with its center of circulation forecast to head northwest toward Tallahassee, Florida, and then over Birmingham, Alabama, on Tuesday morning. However, the strongest impacts from the storm will continue to be to the east of the circulation. And there’s a major airport there: Atlanta’s Hartsfield-Jackson Airport (ATL).Meanwhile, it’s going to take a day or two for operations to get restarted in Florida airports, including American Airlines’ hub Miami International (MIA). That means both Delta and American Airlines are facing a rough couple of days.Delta & Atlanta (ATL)Cancellations are already piling up in Atlanta with 446 departures and 475 arrivals cancelled by 10am Monday, according to FlightAware’s cancellation tracker. Both of these represent over one-third of ATL’s flights, giving it the distinction of having the most cancellations of any airport nationwide. But, as winds and rain pick up through the day, these numbers are likely to get even worse.Those FlightAware numbers only reflect the first 414 Delta cancellations for Monday. However, Delta is already reporting a much larger number:To put this in perspective, Delta cancelled just 10 flights the entire month of September 2016 and operated a jaw-dropping 241 days without a mainline cancellation in 2016.What should you do if you’re flying through Atlanta — or another Southeast airport — over the next few days? Delta has set- p flight change fee waivers for the severe weather.Travel dates: September 6-17Airports included: Albany, GA (ABY); Atlanta, GA (ATL); Augusta, GA (AGS); Birmingham, AL (BHM); Brunswick, GA (BQK); Charleston, SC (CHS); Columbus, GA (CSG); Daytona Beach, FL (DAB); Dothan, AL (DHN); Fort Lauderdale/Hollywood, FL (FLL); Fort Myers, FL (RSW); Fort Walton Beach, FL (VPS); Freeport, BS (FPO); Gainesville, FL (GNV); Georgetown, BS (GGT); Havana, CU (HAV); Huntsville, AL (HSV); Jacksonville, FL (JAX); Key West, FL (EYW); Marsh Harbour, BS (MHH); Melbourne, FL (MLB); Miami, FL (MIA); Mobile, AL (MOB); Montgomery, AL (MGM); Nassau, BS (NAS); Orlando, FL (MCO); Panama City, FL (ECP); Pensacola, FL (PNS); Punta Cana, DO (PUJ); Sarasota/Bradenton, FL (SRQ); Savannah, GA (SAV); San Juan, PR (SJU); Santiago, DO (STI); St. Croix, VI (STX); Tallahassee, FL (TLH); Tampa/St. Pete/Clearwater, FL (TPA); Valdosta, GA (VLD); West Palm Beach, FL (PBI)Rebooked travel must begin no later than: September 30When rescheduled travel occurs beyond September 30, the change fee will be waived. However, a difference in fare may apply. Final travel must be completed by end of ticket validity, one year from date of original issue.If travel cannot be rescheduled within these guidelines, customers may cancel their reservation and apply any unused value of the ticket toward the purchase of a new ticket for a period of one year from the original ticket issuance.That’s right. Even for travel merely connecting through ATL as far out as Sunday, September 17, you can change your travel dates or connecting city. You can even cancel your flight and get a credit toward future flights.For an airport-by-airport breakdown of Delta’s operations, Delta has been posting updates regularly to its News Hub.

With operations shuttered at a main hub and across Florida, these cancellations represent nearly a quarter of American Airlines’ scheduled flights worldwide.MIA airport’s CEO said that the airport “endured #HurricaneIrma gusts of nearly 100 mph. Sustained significant water damage throughout.” NBC News tweeted photos of damage inside the terminal:However, it seems the airport is trying to get operations to resume Tuesday, September 12. The airport posted an update to its Twitter page Sunday night noting that “some airlines will fly personnel and crew members [Monday] in preparation for flights to resume.” However, the “water damage at all concourses, fallen trees, airfield, fuel & other damages” may be too significant to get the airport operational by Tuesday.Like Delta, American Airlines has generous flight change fee waivers for the severe weather.FLORIDATravel dates: September 5-17Airports affected: Daytona Beach, Florida (DAB); Destin / Fort Walton Beach, Florida (VPS); Fort Lauderdale, Florida (FLL); Fort Myers, Florida (RSW); Gainesville, Florida (GNV); Jacksonville, Florida (JAX); Key West, Florida (EYW); Melbourne, Florida (MLB); Miami, Florida (MIA); Orlando, FL (MCO); Palm Beach, Florida (PBI); Pensacola, Florida (PNS); Tallahassee, Florida (TLH); Tampa, Florida (TPA); Sarasota, Florida (SRQ)Must have bought your ticket by September 10Rebook travel anytime between September 5-30You can change your origin or destination city within 600 miles.
