While Labor Day is first and foremost a tribute to the nation’s workers, it is also billed as one of the worst travel days of the year.

Nearly 35 million people will be traveling this weekend, with nearly eighty percent traveling by air. This summer, photographer Kevin Kunstadt began making long exposures of airplanes as they flew over the New York City area at night, creating these surreal and eerily beautiful images that chart the flight paths travelers will take this weekend.
