CNN reported that US federal health officials met a plane landing Wednesday at John F. Kennedy International Airport in New York after passengers reported feeling ill.

Emirates Flight 203, which originated in Dubai, was carrying more than 500 passengers and landed around 9:06 a.m. ET, a source with the Port Authority of New York and New Jersey said.

All passengers were screened, the airline said, and three passengers and seven crew members were transported to a hospital for treatment and evaluation.

“I asked the (flight attendant) for a mask before we even took off, but there was none available,” passenger Erin Sykes told CNN from the plane. “It was so obvious that a large number of people were ill well before takeoff.”

The nonstop flight was a smooth one, Sykes said, so she didn't believe the ailments were related to turbulence or air sickness.

“People were coughing the whole time. Now some people have fevers over 100,” she said. “They should never had been allowed to board.”

While the Centers for Disease Control and Prevention and the Port Authority source said as many as 100 passengers reported feeling sick, the airline said only about 10 passengers had “taken ill.”

“As a precaution, they were immediately checked by local health authorities and those needing medical attention will be attended to,” Emirates said in a statement shortly after the plane landed.

The plane was taken to a “hard standing area,” where paramedics and officials from the CDC were responding to the scene, the Port Authority source said.

The CDC said passengers “complained of illness including (coughing) and some with fever,” and health officials worked with local authorities to take their temperatures and transport those who were sick to a hospital.

The return flight to Dubai will be delayed about three hours, the airline said.
