Air travelers faced delays and cancellations in the Northeast on Monday as storms fired up across the region.
Nationwide, more than 1,030 flights had been canceled and another 4,300 delayed as of 3 p.m. ET, according to flight-tracking service FlightAware.
The disruptions were concentrated at a handful of busy Northeast airports, including hubs for several big U.S. carriers. Delays and cancellations in the region often ripple out to other airports across the nation.
FLIGHT TRACKER: Is your flight on time?
At New York’s LaGuardia airport, more than 300 combined departures and arrivals were canceled as of 2 p.m. ET and a similar number delayed. Those tallies meant about a half of the entire day’s schedule at the airport was either late or canceled, according to FlightAware.
Newark’s Liberty International Airport faced similar problems. Nearly 25 percent of the airport’s Monday schedule was delayed while about 18 percent of the day’s flights were canceled, FlightAware calculated.
The Philadelphia, New York JFK, Washington Reagan National, Baltimore/Washington, Washington Dulles and Boston Logan airports also had above-average delay and cancellation numbers as of early Monday afternoon.
Delays also had begun to spill outside the region, likely a mix of cascading disruptions from the East and from the expanding reach of pop-up thunderstorms across the East on Monday. Detroit, Charlotte and Atlanta were among other big airports where close to 10 percent of the day’s flights were delayed.
Fliers also faced late flights in Dallas/Fort Worth, where between 15 and 20 percent of Monday’s flights were running late as storms fired up there, too.
Fliers should keep an eye on flight schedules throughout the day. Storms were expected to move across the Northeast into the evening, potentially blocking flight paths near major airports.
In anticipation of the poor weather, the nation’s four biggest airlines – American, Delta, Southwest and United – each had flexible-rebooking policies in place for airports in the greater New York City area.
The details varied by carrier, though they generally allowed Monday customers to make one change to their itineraries without paying a change fee or – with some restrictions – a recalculated fare. Southwest’s rebooking policy also included the Philadelphia, Washington and Baltimore airports.
To the west, off-and-on arrival delays at San Francisco appear to have cleared.
