Frontier flight diverted after lavatory leaks, floods cabin: 'Mayday, mayday, mayday'

A Frontier Airlines flight bound for Detroit diverted to Chicago after a lavatory leak flooded the cabin. Reports indicate a water leak from a sink near the front of the plane led to enough water to spread throughout the main cabin.

The incident involved Flight 3655, which had departed Denver International Airport around 10:15 a.m. bound for Detroit Metropolitan Airport before diverting to O’Hare International Airport.

Air traffic control recordings captured the pilot declaring an emergency, noting that the leak had the potential to damage electronic equipment and that landing clearance at O’Hare was requested. The diversion followed confirmation of the water flow into the cabin.

Frontier confirmed the cause as a leaking faucet and said no passengers or crew members were injured. The aircraft was parked at gate M40 for maintenance after the diversion, and the airline planned to dispatch a replacement aircraft to continue the passengers’ trip to Detroit.
