Travelers on the East Coast faced significant delays as thunderstorms caused ground stops at JFK, Newark, and LaGuardia airports. The ripple effect of these delays extended up and down the East Coast, impacting thousands of passengers. Reports from The New York Post indicated that the severe weather conditions led to JFK first grounding flights, followed by Newark and LaGuardia. Newark Liberty International Airport was hit with outgoing flights being shut down until 6:30 p.m., while LaGuardia grounded all planes through 8 p.m.

Philadelphia International Airport and Ronald Reagan Washington National Airport were part of the early cascade of delays, with wait times increasing throughout the day. According to the FAA, JFK experienced departure delays of around 2 hours and 35 minutes. Meanwhile, Newark suffered considerably longer delays, reaching up to 4 hours and 31 minutes, as reported by the PIX11. The storms triggered over 1,500 flight delays in New York alone, and extended across the nation with more than 6,000 flights delayed, and nearly 600 canceled.

The Fourth of July holiday weekend is typically a busy time for air travel, and the Transportation Security Administration expected over 18 million people to travel by air during this period. This year's celebrations were marred for many by the delays and cancellations. LaGuardia Airport informed travelers of the disruptions on Twitter, urging them to check the status of their flights with their respective airlines.

The aftermath of the ground stops continued to affect flights even though the restrictions were supposed to lift in the early evening. The domino effect that began in New York trickled down to other airports, with flights in Washington grounded until 5 p.m., and Philadelphia flights remaining on the tarmac until 6:30 p.m. Despite this, FAA reports suggest, that delays in Philadelphia had decreased slightly to just 1 hour and 15 minutes. The severe weather alert in New York was set to remain in place until 11:59 p.m., adding complexity to the resolution of the day's widespread travel disruptions.
