# Hurricane season and Miami flights

When hurricane season affects MIA, who decides to cancel flights or close the airport, how airline travel waivers work, and what to do when a storm is forecast.

**Hurricane season runs from June 1 to November 30, and the busiest stretch is mid-August to mid-October.** When a storm does threaten Miami, your airline decides whether your flight goes, well before the airport itself shuts. If your airline publishes a travel waiver for your dates, that’s when to move your flight.

## Who decides what

A storm doesn’t close MIA in one step. Three different bodies make three different calls, as the Miami Herald’s hurricane travel explainer sets out:

| Who | What they decide |
| --- | --- |
| Your airline | Whether your flight is delayed or cancelled, flight by flight, depending on the storm’s strength and track |
| The Federal Aviation Administration | Ground stops in bad weather, and closing MIA’s control tower once sustained winds reach 75 mph |
| The airport | Whether the terminals close |

So airlines usually cancel flights while the terminal is still open. Miami-Dade County’s update after Hurricane Milton is a good example: MIA “remains open and operating, although some flights have been cancelled.” Check your flight with your airline before you leave for MIA.

**MIA is not a hurricane shelter.** The airport’s communications director told the Herald that it may not have enough food and water for a storm and its aftermath, and that anyone inside could be moved to a county shelter. Don’t plan to ride out a storm in the terminal. If you have lounge access while you wait, check the published hours in our [lounges directory](https://miaairportguide.com/lounges/) first.

## Travel waivers before a storm

When a named storm heads for South Florida, an airline can publish a **travel waiver** for the affected airports and dates. The notice on your airline’s website says which flights it covers and what you can change for free.

A waiver can appear days before a storm arrives. Before Hurricane Milton, Delta issued its waiver about three days before landfall and waived fare differences, according to a Miami transport operator’s account of that storm. If a waiver covers your dates and your plans can move, change them while other flights still have seats.

If your airline cancels the flight and you choose not to travel, the US Department of Transportation’s refund rule entitles you to your money back, nonrefundable fares included, as long as you turn down the rebooking and any voucher or credit. Ask the airline whether a hotel or meal voucher applies before you count on one.

## Flying into or out of Miami in season

- **For mid-August to mid-October dates,** look up whether your fare carries a change fee before you buy.
- **When the National Hurricane Center puts South Florida in a storm’s path,** check your airline’s site for a waiver that names MIA.
- **On a connection through MIA,** ask the airline to rebook every remaining flight on your booking, not just the cancelled one. Our guide to a [missed connection at Miami](https://miaairportguide.com/guides/missed-connection-at-miami-what-do-first/) explains what to ask for.
- **Before a cruise,** leave a spare day between your flight and the sailing. Our guide to [how early to fly before a Miami cruise](https://miaairportguide.com/guides/how-early-fly-before-miami-cruise/) covers the timing.
- If you’re stuck overnight, our guide to a [cancelled flight at MIA](https://miaairportguide.com/guides/flight-cancelled-at-mia-options-tonight/) covers where to sleep, and our [hotel guide](https://miaairportguide.com/hotels/) lists the hotel inside the terminal and hotels with an airport shuttle.

## What about Fort Lauderdale?

Fort Lauderdale-Hollywood International (FLL) has its own, lower threshold. According to the Herald, the FAA closes FLL’s control tower once sustained winds reach 39 mph, and the airport closes several hours earlier than that so workers can get home safely. Cruise passengers weighing FLL can see the transfer and drive compared in [our Fort Lauderdale guide](https://miaairportguide.com/guides/flying-into-fort-lauderdale-instead-miami-cruise/).
