Here's how each airline does compensation for flight delays, from meals to hotels to ground transportation

• The US Department of Transportation launched a new "airline customer service dashboard" this year.
• It breaks down the different rights passengers have when an airline delays or cancels their flight.

The US Department of Transportation launched a new "airline customer service dashboard" this September following a summer riddled with flight delays and cancellations.

The chart is designed to help passengers navigate the complex accommodation and reimbursement policies of various US airlines when a flight is canceled or delayed.

It may come in handy for the millions of holiday travelers who are likely to see their flights disrupted by this week's impending winter storm. The worst flight delays will be felt on Wednesday and Thursday, AccuWeather meteorologists predict, even in areas not directly hit by the blizzard.

Extreme weather is considered a "force majeure" event out of airlines' control, meaning passengers are not entitled to flight refunds and other reimbursements like hotel vouchers. However, several airlines have announced they are waiving flight change fees for passengers caught in the storm's path.

The new DOT dashboard was published weeks after Transportation Secretary Pete Buttigieg told airline CEOs that the level of flight disruptions this summer was "unacceptable" and that airlines must "provide timely and responsive customer service during and after periods of flight disruptions."

The agency's recent push for passenger rights has triggered multiple US airlines to alter their existing hotel and meal voucher policies, the DOT said.

A spokesperson for Delta told Insider earlier this year that their customer service commitments were already aligned with Buttigieg's requests, adding that the airline has "updated some of our language to be explicitly clear about the services and amenities we provide customers when they are inconvenienced."

United "rewrote its customer commitments to be more clear and readable to travelers," a spokesperson told Insider. The airline will now offer meal vouchers to passengers whose flights are delayed more than three hours instead of four hours, the airline's website shows.

American Airlines has also updated the language in its customer service plan to "clarify" the company's existing policies, a spokesperson said. JetBlue did not immediately respond to Insider's request for comment.

Despite the recent policy tweaks, some major US airlines still do not provide hotel or meal vouchers to passengers whose flights are disrupted due to reasons beyond the airline's control, such as weather. If your flight to or within Europe is delayed or canceled, you may be entitled to reimbursement of up to 600 euros.
