The Federal Aviation Administration is enforcing flight delays and ground stops at John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport, and Philadelphia International Airport on July 27 and 28, 2026. Severe weather and persistent staffing shortages at the New York Air Route Traffic Control Center are cited as primary causes.
Cancellation and Delay Rates at Four Airports
Flight cancellations at the four airports ranged between 20% and 30% during the disruption. Ground holds and delays averaged between 71 and 149 minutes. As of 4:30 p.m. on July 27, roughly 500 inbound flights were delayed and 80 inbound flights canceled across JFK, LaGuardia, and Newark,
with more than 300 delayed outbound flights from the New York City area reported, according to data from FlightAware.
Extended Flight Limits and Waivers
The FAA extended slot restrictions at Newark through the summer of 2027 and at JFK and LaGuardia through late October 2028. It also prolonged relief from minimum flight usage rules at JFK, LaGuardia, and Reagan Washington National Airport until late 2027. These measures allow airlines to operate up to 10% fewer flights without losing airport takeoff and landing slots, addressing operational flexibility amid ongoing staffing constraints.
Causes of Operational Disruptions
The New York Area Terminal Radar Approach Control is operating with only 57% of its
targeted certified air traffic controller staffing. FAA officials say that the current staffing levels have forced controllers to work mandatory overtime and six-day work weeks. Weather complications compounded the staffing shortages, leading to ground stops and flight delays at the affected airports.
The FAA has noted that air traffic control staffing shortages at Newark will not significantly improve before October 2027.
Passenger Impact and Official Statements
Travelers experienced delays exceeding one hour on July 27, 2026, at the four airports. The combination of flight cancellations and ground delays disrupted normal flight operations substantially. An FAA spokesperson confirmed the role of severe weather and controller staffing
challenges at the New York Air Route Traffic Control Center in the disruptions.
Operational measures such as flight limits and regulatory waivers continue to support the management of airport capacity through 2027 and 2028 amidst a protracted nationwide staffing shortage in the air traffic control system.
