Know your rights: When does an airline owe you a refund?

TAMPA, Fla. - A blast of winter weather will likely make the holiday travel difficult. While airline passengers can't control the weather, there are options for how you respond to it.

AAA is projecting air travel will be up by 14% over last year – and with that major winter storm expected to cripple travel on some of the busiest travel days of the year, transportation officials are urging passengers to know their rights.

Earlier this year, the U.S. Department of Transportation launched a customer service dashboard, laying out airline by airline what to expect and how different airlines will treat you if your flight gets canceled or delayed.

Something to be aware of: airlines do not guarantee their schedules, however, airlines do have customer service plans they have to follow. These commitments can include promises to customers in the event of what's called a "controllable" delay or cancelation. Controllable delays are normally defined by issues such as crew problems, cabin cleaning, fueling, or baggage loading. Weather is not normally considered a controllable delay.

For passengers whose flights get canceled, U.S. transportation officials say you are entitled to a refund for the unused transportation. If an airline offers a voucher for future travel instead of a refund, you should ask about any restrictions on that voucher, like expiration dates, advanced booking requirements, and limits on the number of seats. 

Airlines are required to let passengers know about a change in flight status if the flight is scheduled to depart within 7 days.

Airlines are also required to give these status updates 30 minutes after the airline becomes aware of the change.

If a flight is extremely delayed, U.S. transportation officials suggest asking the airline if it will pay for meals or a hotel room. Some airlines offer these amenities, while others do not.

The winter storm will usher in bitterly cold, life-threatening temperatures that will spawn a widespread flash freeze in the Plains, Midwest and East as heavy rain is followed by temperatures rapidly falling below freezing all the way to Florida, which could see its coldest Christmas in more than 30 years.

Travel conditions are expected to become extremely difficult, if not impossible, in many of the areas covered by winter weather alerts due to the combination of snow, high winds and frigid wind chills.
