Bending The Rules Legally.  "Comfort Animals" What if •I• am UNcomfortable with having these mutts around me? US Airways Captain next to me in terminal says comfort animals are normally dogs but can be monkeys. The link below says Elephants can be approved and DOT was/is considering adding pigs to the list. Seriously??
