The festival, sponsored by the Fashion Center Business Improvement District, gave kids a chance to make their own kites from waterproof nylon and plastic and then let them soar from the Port Authority's seventh-floor roof.
"Kite Flight is a celebration of this amazing space, and more importantly it gives kids the chance to fly kites high above the streets of Manhattan," said Barbara Blair Randall, the BID's president.
With plenty of sun and a gentle breeze, Sunday offered perfect kite-flying weather for veterans as well as first-timers.
For those who had trouble getting their kite into the air, experts were on hand to help — including Glenn Davison, 50, who travels from Massachusetts every year to take part in the festival.
"It's a lot of fun, and it's great to see kites flying over the Manhattan skyline," Davison said. "It's just a fantastic experience for everyone, especially the kids."
The event also featured face painting, jugglers and unicyclists, along with a flying yoga demonstration by Om Factory and a concert by Louie & Subanda.
Amanda Moore, from Brooklyn, said she was glad she brought her 4-year-old son Noah to the festival.
"It was a great activity for my son," Moore said. "He's having a blast."
