The union which represents workers at those airports warned the strikes could resume at any time at those locations.
Those companies are contracted to clean planes for United Airlines, handle baggage at the airport and work in wheelchair services.
Headquartered in Manhattan, Local 32 BJ of SEIU, the Service Employees International Union, has 163,000 members, primarily in property service jobs, also known as janitors, along the East Coast.
Several hundred workers planned to walk off the job at NY area airports Wednesday but they suspended the planned strike after talks with American Airlines resumed.
Some of the company's workers at Philadelphia and Denver are also expected to walk out.
Employees for AirServ, PrimeFlight and G2 say those companies have refused to meet with them on a number of issues. The workers, employed through the airline's contractors PrimeFlight Airline Service and Prospect Aviation Services, were planning to hit the picket lines at 11:30 a.m., remaining until 6:30 p.m.
A strike by workers at the four area airports is temporarily on hold, according to reports.
The job actions will continue over the next three days.
