It has been a chaotic past couple of days for travel in the U.S. All major carriers have been impacted by disruptions. United Airlines faced a tech outage, while Delta Air Lines canceled the most flights of any airline worldwide. The issues for Delta are expected to continue, with severe weather on the East Coast expected on Tuesday.
These major carriers are taking precautions. Hundreds of cancellations have already been issued on Tuesday morning, with more disruptions throughout the day.
United Airlines And American Airlines Are Issuing Flexible Rebooking Due To Severe East Coast Storms
A flood watch warning has been issued for New York and New Jersey for Tuesday. According to the National Weather Service, the advisory will remain in effect from 8 A.M. until later in the evening. Isolated tornadoes, strong winds and even hail are possibilities, along with flash flooding.
The New York disruptions will impact travel. On Tuesday, according to FlightAware, LaGuardia canceled 143 departures, along with 139 arrivals. John F. Kennedy International Airport and Newark Liberty International Airport have also canceled hundreds of flights out of precaution due to the upcoming storms.
