An East Coast construction mishap triggered widespread flight delays at Harry Reid International Airport and several other major airports on Monday. A work crew inadvertently severed a backup communications cable in New Jersey, causing the Terminal Radar Approach Control System—a critical tool guiding aircraft during takeoff and landing—to fail.
FlightAware logged 290 delays of 15 minutes or longer at Reid late Monday, representing roughly 19 percent of the day's scheduled operations. Airports in New York, Philadelphia, Boston and New Jersey recorded the highest volume of disruptions.
The ripple effect arrived on the eve of the United Nations General Assembly, where more than 130 international officials are expected to arrive in New York. Reid frequently experiences knock‑on delays when incidents elsewhere in the country hold up inbound flights destined for Las Vegas.
In addition to the delays, FlightAware noted that ten flights departing from Reid were cancelled on Monday, with the service projecting three further delays for Tuesday.
Verizon was the first to report the cable cut, and company spokespeople said repair crews were "actively working" to restore the line. Federal Aviation Administration Director Bryan Bedford cautioned that the restoration could require as long as thirteen hours.
Airport officials advised travelers to verify flight status directly with their airlines.
