According to the Port Authority, the planes sustained minor damage.
Passengers onboard one plane posted pictures to Twitter, saying, "Well looks like my Florida vacation will actually be (sic) at Newark Airport because my @Southwest plane just got hit by another plane on the tarmac."
One person says an airline worker was carrying a piece of metal that fell off the plane when the wings clipped. Another, Bryan Rogers of Weehawken, told Eyewitness News that this happened as both planes were de-icing.
No injuries were reported.
It's still unclear if the incident was weather-related.
