Lavatory Leak Forces Frontier Flight to Divert to Chicago

The aircraft was traveling from Denver to Detroit on November 11 when water from a leaking sink in the forward lavatory began spreading across the cabin floor. The pilots declared an emergency and requested a diversion to Chicago O’Hare Airport.

In a radio transmission, a pilot said the leak was sending enough water into the cabin to raise concerns about the aircraft’s electronics. Passenger footage showed water covering the aisle, and the leak reportedly reached areas behind the lavatory.

A plumber aboard the plane helped shut off the sink, but water had already flowed into the cabin. The aircraft continued to O’Hare and landed safely.

Frontier said the faucet had sprung a leak, causing water to spill over a section of flooring in the plane. The carrier reported that no passengers or crew members were injured.
