Royal Dutch Airlines (KLM) is criticized for having asked a woman who has breastfed on her plane to hide in order to be "respectful of people from other cultures".
Shelby Angel had breastfed her one-year-old daughter last month on a flight from San Francisco to Amsterdam when a flight attendant tried to cover her, Angel wrote in a Facebook post on Sunday.

Angel said her daughter is "a busy toddler who does not like it I do my best to be discreet, but sometimes there are rashes."
She says the unnamed flight attendant has her said: "If you want to continue breastfeeding, you have to assure yourself."
Angel said she needed to be "respectful" after her trip to KLM.
"I was told that I need to be respectful of people from other cultures and that the response of this flight attendant is in line with company policy," Angel said. She said that KLM showed that it has "antiquated values that shame women's bodies."
She added that in the past she had never received any complaints from flight attendants or passengers about her breastfeeding.
KLM clarified in a Wednesday tweet that it allows breastfeeding on flights, but repeated that "we can ask a mother to reassure herself during breastfeeding if other passengers are injured . "

 Airlines such as Delta Air Lines, American Airlines and Virgin Atlantic breastfed aircraft. Many others have no official guidelines, but train their crew to help breastfeeding mothers.
Last year, EasyJet apologized after a male flight attendant had asked a British passenger to be "discreet" while nursing her son, even though the airline explicitly allowed women to breastfeed without disturbance.
Earlier this week, KLM apologized for a tweet from one of its reviewed regional reports stating that you're most likely to survive a crash on a plane.
