According to King5 News a family who where on Flight 171 on Bellingham back home to Phoenix had to leave the aircraft when the boy had an allergic attack.
Because of the allergic attack the flight was delayed. The boy was allergic to a dog on board and began to get very itchy and was scratching all over.
As the family leaved the aircraft some of the other passengers started clapping, laughed and cheered.
Apart from this tragic reaction, what was even more sad is that the boys father is sick with throat cancer and his time is running out. So the trip turn out to not be the nice memory they had hope for.
Everybody has a story with them and you never know what is behind a face.
They travelled with Allegiant Airline who has offered an apology for the other passengers reaction.
