On November 11, 2026, Frontier Airlines Flight 3566, traveling from Denver to Detroit, was forced to make an emergency landing at Chicago O'Hare International Airport due to a leaking lavatory sink that flooded the cabin. The pilot declared an emergency after the faucet burst, causing water to spread along the aircraft floor, raising concerns about potential damage to electronics. A plumber on board managed to shut off the water, but the flooding had already prompted the pilots to divert the flight. Frontier Airlines confirmed that there were no injuries among passengers or crew, and the flight was later expected to continue with a replacement aircraft. The incident highlights the importance of aircraft maintenance and the potential risks associated with onboard systems.
