NEW YORK, June 27 (UPI) — Several passengers on a Delta Airlines flight from Istanbul, Turkey, landed at New York’s JFK Airport Wednesday complaining of nausea, officials said.

The passengers on Delta Flight 73 got sick during the flight and required medical assistance for vomiting and nausea, NBC-TV, New York, reported.

Delta employees were “working closely with these customers to ensure they are well cared for,” the TV station quoted Delta spokeswoman Leslie Scott as saying.

The ill passengers were allowed to move through customs after about 30 minutes.
