As of Thursday, Hurricane Milton downgraded to a Category 1 hurricane after leaving Florida, but it’s still affecting travel on Friday. By Friday morning, over 384 flights within the U.S. are delayed, according to FlightAware, a flight-tracking service.

The hurricane made landfall late Wednesday as a Category 3, leading to the closure of airports, attractions, and other facilities, leaving behind a trail of destruction.

This week, various U.S. airlines have offered travel waivers to passengers traveling to or from certain Florida airports and have increased seating availability for those seeking to evacuate the state ahead of the storm.

Understanding what you’re eligible for in case of a flight delay can be complicated. According to the Department of Transportation (DOT), airlines must refund passengers if their flight gets canceled, but this rule does not extend to delays. Compensation for significant delays is generally left to the airline’s judgment.

Here’s what you need to know about your rights when flights are disrupted.

What should I expect if my flight is delayed?

Though there is no formal policy regarding delays, airlines have made some commitments to compensate travelers experiencing significant delays according to the DOT. The DOT will hold airlines accountable if they do not meet these commitments, although airlines may define significant delays in varying ways, which will affect the compensation offered.

As per the DOT consumer dashboard, if a flight is delayed significantly due to reasons within the airline’s control, the following airlines will rebook passengers at no extra cost and provide a meal, cash, or voucher for delays lasting three hours or more from the scheduled departure:

Alaska, Allegiant, American, Delta, Frontier, Hawaiian, JetBlue, Southwest, Spirit, and United.

The airlines Alaska, American, Delta, JetBlue, and United also pledge to:

• rebook passengers with a partner airline without any additional charges
• provide complimentary hotel accommodations for those affected by overnight delays
• offer free ground transportation to and from the hotel for passengers affected by overnight delays

On the other hand, Allegiant, Hawaiian, Southwest, and Spirit do not offer rebooking on partner airlines but do provide the other mentioned accommodations.

Additionally, Alaska, JetBlue, and Southwest may offer a travel credit or voucher if a delay extends beyond three hours from the departure time.

Frontier will rebook passengers on their own flights only and will offer a meal, but does not provide hotel stays, transportation, or rebooking on partner airlines.

What actions should I take if my flight is delayed?

Occasionally, airlines might provide compensation that goes beyond their formal commitments to the DOT. It’s advisable for travelers to get in touch with their airline directly to inquire about potential compensation in case their flight is delayed due to Milton. Don’t forget to check if your travel insurance or specific credit cards might help cover costs, like hotel stays, in the event of a prolonged delay.
