FlightAware’s cancellation tracker counted 1,276 cancellations in the US on Friday and another 2,327 cancellations Saturday.As Irma neared landfall on the southwest Florida coast shortly after 3:00pm Sunday, flight cancellations reached the 3,000 mark for the day. Five airlines have cancelled more than 40% of their schedule on Sunday: interCaribbean Airlines (87%), Spirit (44%), Allegiant Air (44%), Seaborne (44%) and JetBlue (40%).Crazily enough, the cancellations could get much worse Monday and into Tuesday. Hurricane Irma is expected to speed up the Florida coast on Sunday evening and inland toward the world’s busiest airport by passenger traffic: Atlanta’s Hartsfield-Jackson Airport.What does that mean for the critical aviation hub? Brandon Cosinteno, an aviation meteorologist and owner of Weather Online Network, explains:Irma will continue to move to the North on Monday and will be located near Columbus, Georgia by Monday Evening. That will put Atlanta in the Northeast quadrant of the storm which means the Atlanta area including the Hartsfield-Jackson International Airport will see strong winds and very heavy rainfall. In fact Atlanta is under a Tropical Storm Warning for the first time ever with wind gusts up to 65-70 mph by Monday Evening and Monday Night.By Tuesday a rapidly weakening Irma could bring some heavy rain and gusty winds to Memphis and Nashville.Image courtesy of Weather Online NetworkAt the same time, airports across Florida may still be closed to assess damage and make repairs. Naples airport (APF) has already experienced a 142 mph wind gust and Fort Myers Southwest Florida International Airport (RSW) recorded a 79 mph gust. As the storm moves up the coast, the worst may be still to come for many Florida airports.Once airport repairs are complete, there’s still the issue of missing aircraft. JetBlue doesn’t have a single plane in the state of Florida and most other airlines cleared out their aircraft from vulnerable airports ahead of the storm. So, flights can’t resume until airlines fly aircraft back into the state.All of this is pointing to very rough travel days Monday and Tuesday. That’s the bad news. The good news is that airlines realize this and many have issued change fee waivers. These allow connecting travelers to reroute through other connecting airports, and flexible travelers to change travel dates or times. Some will even let you fly out of another airport.My personal travel plans included an American Airlines flight from Tampa (TPA) to Chicago (ORD) on Tuesday after traveling into the Tampa area this weekend. Hurricane Irma changed those plans. Thankfully, AA’s travel waiver allows airport changes of up to 600 miles, so I was able to rebook my flight out of Atlanta (ATL), where I’m riding out the storm.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

This is allowing him to head straight to the work trip from his evacuation point in Birmingham instead of having to position back to Tampa to fly out. This process was free, quick and easy on Southwest’s website:These are just two examples of airlines allowing common sense changes. However, you can get a lot more creative. Taken to the extreme, say you booked a cheap midweek United flight starting at or connecting through an impacted airport on September 27. Even if there are no operational impacts to the Atlanta airport, by using United’s current waiver, you can change your flights to Friday or Saturday (September 29-30) and save a couple of days of vacation. Or, you can fly out the weekend prior and maximize your trip.Back in January, TPG’s Editor-at-Large Zach Honig used a weather waiver to book an impressive routing, before having to change the flight back due to a scheduling conflict.With some of these options in mind, check your flight schedule and compare it to the following weather waivers.Travel WaiversBelow is a map of all the airports affected by waivers:As of this writing, here are the available travel waivers for this storm:AlaskaTravel dates: September 6-16 [dates extended]Airports affected: Havana (HAV); Fort Lauderdale (FLL); Orlando (MCO); Tampa (TPA)Must have bought your ticket by September 6Rebook travel anytime through September 23 [dates extended]You may request a refund if you choose not to travel at all.Tickets must be exchanged or refunded on or before September 16, 2017.American AirlinesSee website for waivers for Leeward Islands, Puerto Rico, Cuba, BahamasFLORIDATravel 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 5Rebook travel anytime between September 5-30You can change your origin or destination city within 600 miles.

That’s why we recommend paying for flights with cards that have flight delay/cancellation insurance that can reimburse you for weather issues. Top options include the Citi Prestige ($500 per passenger for 3+ hour delay), the Chase Sapphire Reserve ($500 per ticket for 6+ hour or overnight delay) and the Chase Sapphire Preferred Card ($500 per ticket for 12+ hour or overnight delay). My Citi Prestige came in handy a few weeks ago when I got stuck in Japan due to a typhoon-related flight cancellation.
