JFK was a transportation nightmare Saturday night — thanks to cabbies abandoning their taxi stands to join the immigration-ban protest and the Port Authority suspending some AirTrain service.

“You know any good car services that’ll take me to Jersey?” said a stranded Marshall Ross, 38, of Old Bridge, NJ as he waited in vain at an abandoned taxi stand outside Terminal 7.

“Our 19,000-member-strong union stands firmly opposed to Donald Trump’s Muslim ban,” the New York Taxi Workers Alliance said in a statement announcing what was essentially an en masse hack walkout.

“As an organization whose membership is largely Muslim . . . we say no to this inhumane and unconstitutional ban.”

“Drivers stand in solidarity with refugees coming to America in search of peace and safety,” the statement said, calling the ban “pure bigotry.”

Complicating travels, AirTrain service was briefly suspended between Jamaica and JFK, but it was reinstated in less than an hour after Gov. Cuomo ordered the PA to restart it.
