Rivera said pro-Palestinian protesters are expected to cause delays at JFK Terminal 4 (departures). 

"There are planned protests today and will cause delays. We don't want anyone to miss their flights! Safe travels and Happy New Year," he said. 

Social media reports show NYPD officers only allow people with an "Employee ID or Boarding pass" to enter train stations to JFK Airport. 

A pro-Palestinian vehicle convoy appears to be heading to the airport. 

Some pro-Palestinian protesters are calling NYPD officers "NYPD, KKK, IDF, You're all the same."  

"Reports of massive law enforcement mobilization around strategic entry points into JFK airport to protect travelers from pro-Hamas protestors. This includes resources from NYPD, NY State Police, Port Authority Police, National Guard, and multiple state and city resources. May God bless them all. Enough is enough. Long past due to take back our streets. Thank them when you see them," one X user said.
