So they refused to follow instructions and got thrown off the plane. But, but, but they had a good excuse! Learn to behave in public.
Sometimes flight attendants are just nasty. I wouldn’t be so quick to assume the sisters were being insubordinate. What was wrong with the flight attendant just being a bit kinder? Also, why weren’t the sisters seated together? That’s what I wonder. I think the airline should be ashamed. Really. I’ve had a few bad experiences. Once a person was traveling with their cat and it got loose in the cabin...it was hanging out under our seats. My husband is highly allergic. We told them we thought the cat should have to stay in a crate or whatever...now we know that cats are more important than people!
