Adverse weather conditions, including severe thunderstorms, heavy rainfall, and unfavorable weather, caused widespread disruption to travel plans for Americans nationwide on Sunday. The airports most significantly affected were Newark Liberty International, John F. Kennedy International, and LaGuardia Airports, which all serve New York City. The impact was extensive, resulting in the cancellation of more than 1,600 flights across the United States.
Among all the airports in the US, Newark Liberty International Airport bore the brunt of flight cancellations on Sunday with the maximum number of flight cancellations.

However, the issues faced by travellers extended beyond flight disruptions as they encountered problems in receiving their baggage as well.
One passenger from Chicago, who travelled through Newark, reported to the New York Post that dozens of fellow passengers experienced extended waits of more than two hours to retrieve their luggage.
Surprisingly, only about a third of the passengers received their baggage, while the rest were left without theirs, seemingly missing.

Following closely behind Newark Liberty, John F. Kennedy International and LaGuardia Airports ranked second and third, respectively, in the country for the highest number of flight cancellations.

New York City and its surrounding areas experienced significant rainfall due to the thunderstorms, with most regions receiving between one and three inches in total.
Some areas even saw as much as five inches of rain by nightfall. Unfortunately, the severe weather and subsequent flooding led to the loss of one life and caused approximately $50 million in damages, according to Governor Kathy Hochul of New York.

According to media reports citing FlightAware data, over 8,500 flights experienced delays due to severe weather conditions, including intense thunderstorms.
