Travelers will no longer face refund challenges, as the U.S. Department of Transportation has implemented new regulations requiring automatic cash refunds for domestic flights delayed by three hours or more and international flights delayed by six hours or more. Canceled flights also qualify for refunds. Additionally, passengers are entitled to refunds for checked baggage fees if the bag is not delivered within 12 hours for domestic flights or 30 hours for international flights. These regulations ensure that passengers receive compensation for flight disruptions and promote transparency in airline pricing.
