A boy on a vacation with his dying father was back home in Arizona on Thursday, days after the 7-year-old suffered a dog allergy attack and the family was removed from a flight home to applause from passengers, his mother said.

The trio was at the tail end of a bucket-list vacation to the U.S. Northwest so the boy's father, George, who has terminal throat cancer, could visit family, when the child suffered a severe allergy attack from being near a dog brought on the plane, she said.

"Shame on you for being so cruel," Christina Alvarado wrote on Facebook after her family was taken off a Monday flight from Bellingham, Washington, to the Phoenix area.
