(CNN)Several water fountains were shut down at a Cleveland airport after passengers aboard a Frontier Airlines flight became sick, airport officials said.
At least six passengers who traveled on Tampa-bound Frontier Airlines Flight 1397 on Tuesday fell ill after leaving Cleveland Hopkins International Airport.
The passengers, who were not traveling as a group, were vomiting by the time the plane landed, said Janet Scherberger, a Tampa International Airport spokeswoman.
While health officials have not confirmed what caused the illness, officials at the Cleveland Hopkins International Airport are looking into whether the water fountains may have contributed to it.
