The mother of a young baby in the US says she has been put on the country's official no-fly list after an incident involving a dirty nappy.
In a post on Facebook, Doctor Farah Naz Khan alleges the incident took place in first class on a United Airlines flight.
"I had to change baby's poop diaper in the back bathroom and I disposed of it in a scented diaper disposal bag inside the bathroom trash. When I came to the front, the flight attendant berated me for throwing away a poop diaper on the plane. He said it was a 'biohazard' and that I should retrieve it if I can," Khan said.
"So there I am, fishing her poop diaper out of the back bathroom. I asked the other flight attendant in the back if he could give me an extra garbage bag to put this in so I could keep it with me to throw away after the flight. This flight attendant told me that throwing the diaper away in the bathroom is what we're supposed to do, so when I confronted the initial flight attendant about this, he yelled at me again and said he didn't want to deal with me."
Khan described the experience as "horrific". But the confrontation continued even after the flight had landed.
"Fast forward three hours, and he's calling me on my cell from a United Airlines 1-800 number and saying I've been placed on the no-fly list because of a 'biohazard incident'. And he cursed me and my family. And said 'YOU people bring your families everywhere. You should stop flying and just drive. I can hear your obnoxious baby in the background right now'," Khan claimed.
In a tweet to the airline, Khan asked how the flight attendant - described as a white male - managed to get her phone number.
While the incident took place on a United Airlines branded aircraft, it was operated by Mesa Airlines, which operates some regional services on behalf of United.
A United Airlines spokesperson referred all media to Mesa.
"The details as described by our customer do not meet the high standards that Mesa sets for our flight attendants and we are reviewing the matter," a Mesa spokesperson said.
