Delta Flight Returns to Gate After Deicing Fluid Leaks Inside Cabin and Soaks Passenger

A Delta Air Lines flight bound for Jacksonville, Florida was forced to return to the gate at New York LaGuardia Airport after deicing fluid unexpectedly leaked into the passenger cabin and soaked a traveler, according to reports.

The incident occurred on Delta Flight 1307, an Airbus A220-100 scheduled to depart LaGuardia on January 18, 2026, during routine winter weather operations. After the aircraft underwent a mandatory deicing procedure on the ground — designed to remove ice and snow from critical surfaces — some deicing fluid reportedly found its way into the fuselage near the wings, resulting in one passenger becoming wet.

Audio recorded between the flight crew and air traffic control captured the pilot describing the situation: “We had a bunch of deicing fluid leak inside of the aircraft and soak a passenger,” before adding that the traveler might simply need “a new pair of pants” after the incident.

Delta spokespersons later clarified that the amount of fluid involved was small and that the chemicals used — a propylene glycol-based mixture common in U.S. winter operations — are considered non-hazardous to passengers. Nevertheless, the airline chose to return the aircraft to the gate as a precautionary measure while ground crews inspected the situation and assisted the affected passenger.

Following the inspection and cleaning, passengers were re-accommodated aboard a separate aircraft, and the flight eventually departed LaGuardia approximately three hours later en route to Jacksonville.

Deicing is a standard winter safety protocol at northern U.S. airports like LaGuardia, where aircraft are sprayed with heated fluids to ensure ice and frost do not compromise aerodynamic performance. While rare, leaks of deicing fluid into the cabin represent an unusual deviation from normal procedures and highlight how challenging winter operations can be for airlines managing tight schedules and weather constraints.
