Newark Liberty International Airport is open. But right now, it barely feels like it.
Hundreds of travelers woke up Monday morning to a nightmare — delayed flights, packed terminals, and a cascade of cancellations that have turned one of the busiest airports on the East Coast into a pressure cooker. The question spreading fast across social media and search engines — is Newark airport closed — has a simple answer: no. What is closed, at least for now, is LaGuardia Airport in New York, and the fallout is hitting Newark hard and fast.

A Deadly Crash at LaGuardia Changed Everything
Just before midnight Sunday, an Air Canada Express regional jet carrying 72 passengers and four crew members collided with a Port Authority fire truck on Runway 4 at LaGuardia Airport. The plane had just touched down from Montreal when it struck the firefighting vehicle, which had been cleared by air traffic control to cross the runway. Audio recordings captured the moments before impact — a controller heard urgently ordering the truck to stop, over and over, until it was too late.
Both the pilot and co-pilot were killed. Forty-one people were transported to area hospitals. The fire truck was knocked onto its side. The front of the aircraft was demolished.
By Monday morning, LaGuardia was shut down entirely. Federal aviation authorities issued a full ground stop, and the airport announced it would remain closed until at least 2:00 p.m. Eastern Time — a timeline that many aviation officials expect will be extended as federal investigators comb through the wreckage and review every communication between the aircraft and the tower.
Newark Is Absorbing the Overflow
With LaGuardia dark, incoming flights had nowhere to go. At least 18 aircraft were diverted, most of them routed to John F. Kennedy International Airport or Newark Liberty. That diversion, combined with the already-fragile state of Newark’s own operations, has made Monday at EWR extraordinarily difficult.
As of this morning, 168 flights had been delayed at Newark and 10 had been cancelled outright. Routes to Chicago, Miami, Orlando, and major Texas cities were among the hardest hit. United Airlines, which operates its primary East Coast hub at Newark, is bearing the heaviest burden. American Airlines, Delta, JetBlue, Spirit, and Frontier are all showing significant disruption across both departures and arrivals.
The delays are not small. Many flights are running more than an hour behind schedule. Travelers whose connections depend on tight timing are facing cascading problems — missed legs, lost hotel bookings, and no clear path forward on a day when every alternate flight is already filling up.
Newark Was Already Struggling Before Today
Today’s chaos did not arrive out of nowhere. Newark Liberty has spent the better part of the past year operating at or beyond its limits. The FAA extended a cap on hourly flight operations at the airport through October 2026, citing persistent staffing and equipment challenges that have made Newark one of the most delay-prone airports in the entire country.
Air traffic controllers across the nation are thousands short of targeted staffing levels, and the facility that manages Newark’s airspace has been stretched thin. Runway construction, which resumed earlier this year, has added further complexity to an already crowded operation.
Starting March 28, travelers using the AirTrain to reach Newark will face another hurdle — a full maintenance shutdown of the rail link, with shuttle buses replacing train service for the weekend. Passengers relying on NJ Transit or Amtrak connections should plan around that disruption now.
TSA Staffing Adds Another Layer of Uncertainty
On top of all of this, Transportation Security Administration officers are working without full pay. A partial federal funding shutdown has affected the Department of Homeland Security, and TSA personnel missed a paycheck earlier this month with no resolution in sight. Long lines at security checkpoints were already a concern heading into spring break travel season. Today, with a surge of diverted and rerouted passengers flooding terminals that were already at capacity, those lines are going to get longer.
Travelers are being urged to arrive at Newark at least three hours before any domestic flight and even earlier for international departures. Gate assignments are shifting frequently, and passengers should keep airline apps open and notifications turned on throughout the day.
What Investigators Are Looking At
The National Transportation Safety Board dispatched a full investigative team to LaGuardia early Monday morning. The central question under review is straightforward but deeply troubling: how did a fire truck get cleared to cross an active runway at the exact moment a commercial jet was landing on it?
Investigators will examine air traffic control audio and transcripts, ground vehicle tracking data, lighting conditions at the time of the collision, and whether standard runway incursion protocols were followed. The aircraft’s flight data recorder and cockpit voice recorder have already been secured. Results from the formal investigation will take months, but preliminary findings could emerge within the next several days.
Aviation safety experts note that runway incursions — incidents where aircraft and ground vehicles occupy the same stretch of pavement simultaneously — remain one of the most serious and preventable hazards in commercial aviation. LaGuardia’s tight layout, with short runways and dense taxi routes, has long been cited as a factor that demands exceptional coordination between controllers and ground crews.
What to Do If You’re Flying Today
If your flight is out of Newark, do not assume it is on time. Check your airline’s app or website before leaving home. If your flight has been cancelled, call the airline directly rather than waiting at the airport — hold times will be long, but airport lines will be longer.
If you were booked into LaGuardia and have been rerouted to Newark, confirm your new terminal and gate before you arrive. Terminals at EWR are not connected airside, so knowing your exact location matters.
For travelers with flexible plans, waiting until Tuesday or Wednesday to fly may result in significantly less disruption. The backlog created by today’s events is expected to ripple through flight schedules for at least the next 48 hours.
Newark airport is not closed today. But with 168 delayed flights, a neighboring airport shut down by a fatal crash, and federal staffing shortages straining every checkpoint and control tower in the region, it is running at the edge of its capacity — and every traveler passing through it right now is feeling that.
