“We’d like to declare an emergency, our forward lav sink has sprung a leak and it’s spraying so much water that it’s flooding the entire cabin area in the back and we are worried about electronics,” he continued.

The plane landed safely and no injuries were reported, Frontier told The Post.
“Earlier today as Flight 3566 was enroute from Denver to Detroit, the faucet in the forward lavatory sprung a leak, which caused water to flow along part of the aircraft floor,” the airline said in a statement.
“As a result, the captain requested an emergency landing at Chicago O’Hare. The flight landed safely and no injuries were reported among passengers and crew.”
