Port Authority spokesman Joe Pentangelo says Delta Air Lines Flight 468 from San Francisco to New York with 171 passengers landed at JFK Airport on Monday night (1140 AEDT Tuesday).
Pentangelo says the Boeing 757 was evacuated and taken to a remote part of the runway where it was swept and found to have no explosives.
Delta spokeswoman Lindsay McDuff said another airline received the threat regarding Flight 468 and that proper security procedures were followed.
She said Delta also currently operates a JFK to Tel Aviv flight under the same flight number and was in the process of boarding.
Pentangelo says that plane also was searched and cleared.
