JACKSONVILLE, Fla. -- Breast-feeding mothers held "nurse-ins" Tuesday morning against Delta Air Lines at Jacksonville International Airport and more than a dozen other airports across the United States.

The woman are upset because a nursing mother was removed from a Delta commuter flight operated by Freedom Airlines from Burlington, Vt., to New York City last month.

A flight attendant asked Emily Gillette to cover up as she was feeding her 1-year-old, and when she complained, she was asked to get off the plane.

A handful of mothers breast-fed their babies while sitting outside the Delta ticket counter at JIA.

"I think that it's a woman's right to breast-feed her baby wherever she wants to," Sierrra Malnove told Channel 4. "That's what our breasts are for -- for feeding our babies."

"I don't think it should be an issue to breast feed in public," nursing mother Rebecca Walls said. "My baby was born at 31½ weeks -- two months premature. Had it not been for breast-feeding, I don't think he would have made it as far as he has today."

The "nurse-ins" were also scheduled at airports including Burlington, New York City, Baltimore, Detroit, Nashville, Minneapolis and Columbus, Ohio.
