Heavy thunderstorms forecast around New York City today have triggered a travel alert by airlines.

Delta Air Lines warned of delays due to likely air traffic control restrictions throughout the region, including the international gateway airports of JFK and Newark Liberty.

Passengers are being advised to check the status of their flights.

Both Delta and American Airlines have issued weather waivers to enable flight changes with no fee across airports in the New York City region.

“Thunderstorms throughout the north-east will likely prompt air traffic control initiatives and routeing delays for flights in and out of the region late Wednesday afternoon and evening,” Delta said.

“JFK International, LaGuardia airport, Newark Liberty, Newburgh and White Plains are all included in the waiver.

“The waiver allows customers with flexibility in their travel plans to make a one-time change to their itinerary without incurring a change fee.”

Delta added: “Using the latest weather forecasts, operations teams will make informed decisions on any potential adjustments to flight paths and scheduled departures.”
