As a significant winter storm approaches, airlines across the U.S. have canceled nearly 2,000 flights, with disruptions particularly impacting major hubs such as DFW and Philadelphia International Airport. Travelers are advised to monitor flight statuses and check for travel waivers issued by airlines, including Delta and American Airlines, which are allowing free rebooking due to expected severe weather. The storm is predicted to affect over 40 states, prompting airport officials to prepare for widespread travel chaos. Passengers are also encouraged to understand their rights in case of cancellations and delays.
