Overview
- Frontier Airlines Flight 3566, which was en route from Denver to Detroit on Nov. 11, declared a mayday after a forward lavatory faucet sprang a leak and water spread along part of the cabin floor.
- LiveATC audio and passenger video captured the pilot’s mayday call and footage showing water pooling in the aisle and soaking sections of the cabin.
- Frontier confirmed the captain requested an emergency landing at Chicago O'Hare and said the flight landed safely with no injuries reported among passengers or crew.
- Some outlets reported the jet as an Airbus A321neo with tail N688FR and said a passenger who was a plumber helped shut off the sink, but those details come from limited sources and are not fully corroborated.
- Aviation safety guidance treats cabin flooding as an immediate hazard because liquid can reach avionics or flight-control systems, and past incidents have prompted crews to land quickly for inspection and maintenance.
