New York flights cancelled today (July 22): Hundreds of flights scrapped, 2,000+ delayed as storms bring travel chaos to the Northeast. Check details

Severe thunderstorms sweeping across the US Northeast have once again thrown air travel into chaos, with New York flights cancelled and delayed in large numbers as dangerous weather batters major airports. Travelers flying through New York and other East Coast hubs are facing hours-long disruptions after the Federal Aviation Administration (FAA) implemented traffic management measures to keep flights safe.

If you're flying today, it's worth checking your airline's status before leaving for the airport, as New York flights cancelled continue to affect thousands of passengers.

Why are New York flights cancelled?

A powerful line of thunderstorms moved across the Northeast, bringing heavy rain, lightning, strong winds and poor visibility. The severe weather forced the FAA to slow air traffic into some of the country's busiest airports.

The biggest impact has been felt at New York City's three major airports:

• John F. Kennedy International Airport (JFK)
• LaGuardia Airport (LGA)
• Newark Liberty International Airport (EWR)

The FAA introduced ground delays and temporary traffic restrictions to maintain safety while storms passed through the region.

FAA issues ground stops and delays

The FAA temporarily halted or slowed arrivals and departures at several airports across the East Coast as thunderstorms intensified.

Besides New York, airports in cities including Boston, Philadelphia, Washington DC and Baltimore also experienced operational disruptions, creating a ripple effect throughout the national air travel network.

Because many aircraft operate multiple routes each day, delays in one city quickly spread across the country, leading to even more New York flights cancelled and rescheduled.

Hundreds of flights affected across the Northeast

Flight tracking services reported hundreds of cancellations and thousands of delays throughout the Northeast as airlines struggled to keep operations running safely.

Passengers traveling through New York experienced some of the longest delays, with many flights pushed back by several hours while others were cancelled altogether.

The disruption wasn't limited to domestic travel. Several international departures and arrivals were also affected due to aircraft and crew being out of position.

Manchester-bound passengers also impacted

The disruption stretched beyond the United States.

Passengers flying between Manchester Airport in the UK and New York also faced delays after weather-related disruptions affected inbound aircraft. Several transatlantic services arrived late, while some departures were rescheduled because planes were delayed reaching Manchester.

Airport authorities advised passengers to monitor airline updates before heading to the terminal.

Airlines urge passengers to check flight status

Major US airlines have encouraged customers to check their booking before leaving home, as weather conditions remain unpredictable.

Many carriers are offering flexible rebooking options for passengers whose flights have been delayed or cancelled because of the storms.

Travelers should:

• Check their airline's app or website before departure.
• Allow extra time at the airport.
• Monitor weather forecasts.
• Sign up for airline notifications to receive real-time updates.
• Weather remains the biggest challenge

Summer thunderstorms are one of the leading causes of air travel disruption in the United States. Unlike snowstorms or hurricanes, thunderstorms can develop rapidly, making it difficult for air traffic controllers to predict exactly when airports can safely resume normal operations.

Even after storms move away, congestion often continues for hours as airlines reposition aircraft and crews.

That means New York flights cancelled today could continue to affect schedules well into the evening and even into the following day.

Will more New York flights be cancelled?

Forecasters say additional thunderstorms remain possible across parts of the Northeast, meaning further delays cannot be ruled out.

While airport operations are expected to gradually recover as weather improves, travelers should remain prepared for last-minute schedule changes.

If you're planning to fly through JFK, LaGuardia or Newark, checking your flight status before leaving for the airport remains the safest option, especially as New York flights cancelled continue to dominate travel updates across the region.
