The sick passengers had symptoms that included cough and fever.
Emirates flight 203 was traveling from Dubai to NY and landed shortly after 9 a.m. Wednesday.
The reason why these passengers and crew fell ill, whether food poisoning or flu, has not been released.

The criminal complaint, filed in Los Angeles, alleges that the hackers committed several attacks from 2014 until 2018. The entertainment groups were targeted because of movies that depict the North Korean government unflatteringly.

New York City Mayor Bill de Blasio had been briefed on the incident, his spokesman Eric Phillips wrote on Twitter.
Officials say passengers from the two flights on Thursday afternoon who weren't sick continued on with their travel plans.
Photos from passengers show rows of ambulances and firetrucks on the tarmac.
After spending about an hour or more on the tarmac, everyone on the flight filled out CDC paperwork, deplaned individually, and allowed medical personnel to take their temperatures.
A New York Police Department counterterrorism division tweeted it was monitoring what appeared to be a "medical situation".
U.S. media reported that around 500 passengers were on board the flight.
