American Airlines flight attendant bitten by emotional support dog

An American Airlines flight attendant was bitten by an emotional support dog on a flight from Dallas to North Carolina Monday, prompting union calls to further tighten rules on in-flight animals. The unnamed male flight attendant required five stitches on his hand when he returned to Dallas. The type of dog was not disclosed. "What happened on yesterday’s American Airlines flight is completely unacceptable and inexcusable,'' the Association of Flight Attendants-CWA said late Tuesday. The union said it has long supported the use of trained service animals to help passengers but said the industry needs standards for the less-defined category of emotional support animals. Critics have complained passengers are able to get instant certification for an emotional support animal, and that many aren't properly trained. <br/>
