Port Authority airport workers held a march to demand wage increases on Friday.
32BJ union workers and some local lawmakers marched 10 miles from JFK to LaGuardia on the anniversary of Martin Luther King Jr.'s assassination.
They're calling on American Airlines, JetBlue, and United Airlines to provide raises to workers who make less than $9 an hour and provide benefits.
Several airlines agreed to both when they signed a deal with the Port Authority back in January, but so far only Delta Airlines has made good on the promise.
"The changes are very, very basic. These workers need to have a living wage, they are earning minimum wage or less, they do not have health insurance, they do not have retirement benefits, they should have that too," said Hector Figueroa, president of 32BJ.
"It's a shame that the people that make so much money off the backs of the poor hardworking people don't see that they shouldn't be forced to do it, they should do it," said Rep. Charles Rangel.
The march was a follow-up to the union's protest back in January, in which dozens were arrested for blocking a bridge in an act of civil disobedience, including Rangel.
